Gus gets this treatment to some extent, with some fans seeing him as a Broken Bird who was driven to evil by the Cartel's murdering his business partner, who is also loosely implied to have been his lover, ignoring the fact that he was shown to already be a meth dealer even before this happened, and is implied to have had a dark past of some kind in Chile (though the latter one's never actually elaborated on, probably contributing to Gus being seen this way). Even after revealing in the prequel that he had sociopathic tendencies as a child (torturing an animal to death for eating his fruit), people still defend him and blame all his faults on the Cartel. Some fans even blame Walt for ruining their business relationship, even though Gus basically forced him into it and was clearly planning on getting rid of Walt as soon as he could be replaced. They also seem to forget that Gus started their feud by having a child murdered and not understanding Walt's decision to save Jesse when he tried avenging that child.
While Gus has one or two softer moments, Better Call Saul goes out of its way to show that he is a cruel and ruthless criminal with very few scruples. Despite that, many fans still openly root for him and downplay his evil. In particular, you’d think it would be hard for anyone to defend Gus after he threatened Nacho's dad, confessed to sadistically torturing an animal as a child and intended to kill Werner's innocent wife had Mike not intervened.
Many fans like to forget that Mike technically is a villain even if he's largely one of the punch-clock variety. It ranges from those who may downplay his villainy and those who go as far as to say that he doesn’t even count as a villain at all based solely on his goal of leaving his granddaughter a nest egg, despite the fact that he is still ultimately a cold-blooded murderer working for a drug lord and, as Better Call Saul revealed, a former Dirty Cop who only left after his activities inadvertently got his son killed, which makes it hard to argue for why he actually would be any less villainous than any other characters.
While very few fans will defend his more pathetic and less impressive actions as Gene Takavic/Viktor St. Claire, some fans will act like his previous identities: Jimmy McGill / Saul Goodman were almost saints that simply had bad luck.
No matter how many lows he sinks to or how many terrible things he does, many fans will excuse Jimmy for his crimes and blame all of his unsavoury actions on Chuck, while ignoring the fact that, like Walter White, Jimmy had the perfect opportunity to avoid a life of crime for a legitimate path. His chance to clean himself up as a lawyer at Davis and Main, only to instead embrace the path of an Amoral Attorney, shows it isn't just Chuck he'd need to fight, but also his own worst impulses.
Many try to paint Saul as a victim who only did terrible things because he was afraid of Walt, ignoring that he tried to convince Walt to come back to cooking when he had quit and repeatedly suggested Walt kill people so he could save himself from going to prison. This tendency got more pronounced after Better Call Saul detailed how "Saul" is a mask for a very traumatized, self-loathing man, so people will forget all the sleaze and cowardice.
Some fans still regard Walter as a hero who does everything for his family even when his actions say otherwise and he himself confesses in the finale that he has been making drugs because he enjoyed it and was good at it. Vince Gilligan himself lampshaded this, saying in a 2022 interview that the more time passes since the show's conclusion, the more he doesn't understand why Walt was ever considered a sympathetic character or why some fans don't realize that Walt brought most of his misfortune down on himself.
Skyler mostly got the Ron the Death Eater treatment during the original run of the show, but over the years she's undergone Character Perception Evolution, with many newer fans and even fans during the series' original run coming to sympathize more with her... and to make up for the infamous hatred she (and her actress) used to receive, now many fans see her as an innocent saint who suffers from an abusive husband and blatantly ignore her obvious flaws like her hypocrisy and greed.
Jesse also gets a good deal of Draco in Leather Pants from people — apparently, realizing that you're a bad guy but continuing to cook meth and doing bad things that aren't as bad as the other criminals you work with makes you a good person. Actually discussed in-episode: when Jesse wants out of the operation with his cut of the money, Walt points out that it's still drug money he'd be taking and asks why he would want it if he's "so pure, with such emotional depth". To Jesse’s credit though, after he gets the money he actually takes what Walt said at face value and he tries to rid himself of it. Peter Gould confessed in the "Gloves Off" podcast that this tendency crossed over to the writer's room as well, as they liked Jesse so much they were mentally absolving him of everything he did.
A few people actually admire Todd, despite the fact that he's a ruthless killer with a total Lack of Empathy, mainly due to his dorky charm.
While Hank isn't evil, many fans like to ignore his flaws such as his hypocritical behavior, like when he thought Hugo the janitor was a scumbag for smoking weed but was perfectly fine smoking illegal Cuban cigars. His poor treatment of Marie in Season 4 is often forgotten, ignored, or justified due to his mental state. This is especially true in Season 5 where he tries to force Skyler into a confession and shows no concern over Jesse's possible death. Regardless of his methods, it's questionable whether we should side with him in his investigation as his primary motive seems to be spite against Walt. While Walt should be punished for his actions, it doesn't seem like any lives would be improved by Hank catching him after he retired. By going solo in his quest to bring down Walt, then later roping in Gomez but not involving the DEA, he got Gomez and himself killed. He was aware of whom Walt had killed and that he must still have allies, yet took Gomez into a deadly situation without arranging any backup, entirely because he personally wanted to take Walt down. He is also shown taking advantage of his power to bully Wendy the prostitute for no other reason than he can. He’s also an unrepentant casual racist. All the way back in the pilot, his mean spirited mocking of Walt and disdain for his life is part of what pushed Walt into Heisenberg in the first place. Despite all of this, many Breaking Bad fans will tell you that Hank's some kind of saint.
Ever since The Reveal that Chuck is the one who decided to not hire Jimmy at HHM and that he actually likes Jimmy very much, many viewers have been willing to overlook Howard Hamlin's more jerkass moments and behavior, like sending Kim to the "cornfield" twice, or the way he and the rest of the board behaved when choosing which pupil to award with the scholarship. Many are willing to reinterpret him as a selfless (to a certain extent) man who's had to take a bullet or two for his partners thanks to the McGills' antics. Given that Chuck was set up to be Jimmy's main friend and the extent of his betrayal, this is sort of understandable.
Lalo. Even though he's a quite obviously a sociopathic murderer, he's a charming, affable killer with a hidden soft side (see his interactions with the people in his complex). Of course, there are also those who were drawn in by Tony Dalton's good looks and charisma, which he uses to great effect. This comes to a head in the Season 6 mid-finale where people seem more furious with Kim and Jimmy to an extent for getting Howard killed, content to overlook the person who actually pulled the trigger and the fact that Kim and Jimmy both attempted to get Howard to leave the house in a failed attempt to save him.
Kim tends to be treated by some as a pure, virtuous innocent who is far too good for Jimmy and is being "destroyed" by her association with him. While this may have been more valid in early seasons (and even then, Word of God is that Kim isn't without her own dark side, it's just much better hidden), it starts becoming a lot less the case in later ones, especially in season 6, as she begins encouraging and enabling Jimmy's worst tendencies while making decisions of her own that leave even Jimmy feeling uncomfortable. Apparently Rhea Seehorn and Bob Odenkirk had fun joking about it, as when Jimmy screwed up it was seen as his inevitable downfall, but whenever Kim screwed up (eventually leading to her own downfall), it was always dismissed.
Michael McKean himself has stated multiple times that he completely loses interest in a conversation if a person tries to act like Chuck is some nice, good man who didn’t hurt his brother for most of Jimmy’s life. Just don’t treat the character as a one-note monster either.
