History BaseBreakingCharacter / Supernatural

** The blame game may have been pretty arrogant, but Sam had something of a point. Dean's only reason for not ''helping'' Sam was because the "demon bitch" was a dealbreaker, ignoring how Ruby had saved them countless times. Dean provoked the fight simply because he refused to reign in his phobia, and Sam was clearly being affected mentally by the demon blood. Calling him a monster was not a smart choice.
** There was a bit more to it than that. Dean found out that said "demon bitch" was getting Sam to drink demon blood, and if the fact that it's demon blood isn't enough to indicate that ingesting it is a horrible idea, there's also the fact that the stuff gives him clearly unnatural powers, apparently alters his mood and cognitive capability, and is highly addictive to the point Sam goes through withdrawals without it and requires a detox in Bobby's demon-proofed basement each time he's trying to get off it. She was also egging Sam on in what was clearly becoming a dangerous and downright obsessive vendetta against Lilith, whom it was stated Ruby had dealings with in the past. Not to mention that by this point, Dean had spent what amounted to forty years in HELL, giving him a very clear inside view of the process that turns humans into demons. He had a number of things to base his judgement on, and while he certainly didn't handle it the best way, it turned out he was right not to trust her.
** Sam has also struggled in this regard due to the NonPOVProtagonist issues. Not that Sam never gets perspective, and he does do legitimately dickish things on occasion. However, he tends to have a lot more plot revolving around him, and we tend to see a lot of more of Dean's mindset/emotions. Thus, when the brothers disagree, it tends to be a lot easier to understand Dean's perspective than Sam's, and therefore conclude that [[ProtagonistCentredMorality if Sam is going against Dean, he's "wrong."]] It doesn't help that since Dean's both a KnightTemplarBigBrother and a ParentalSubstitute whose life largely revolves around Sam, anytime Sam disagrees with him or does something hurtful he looks like an UngratefulBastard. Taken to extremes by [[VocalMinority some fans]] who cite Sam as selfish for "sins" such as going to college or, uh, [[spoiler:''dying'' in Season 9]] because Dean was against those things.

** It's not so much that [[spoiler: Sam died,]] that fans were upset about, it's that when Dean saved him, Sam held it against him for the whole of the season. Yes, Dean was in the wrong for [[spoiler: tricking Sam into letting an angel possess him]], but all things considered, when Dean was pushed at multiple points by various parties to get over a number of Sam's less than admirable actions season after season, such as Sam running off with a demon who was only using him, killing Lilith and releasing Lucifer, abandoning Dean in Purgatory for a year to try to live a normal life and expressing more angst over the fact that Dean turned to others for help than any true regret for essentially abandoning his brother and friends in the first place... well, it comes off as somewhat disproportionate.
** His not making any effort to find Dean after the end of Season 7 naturally ticked a lot of people off. And then there's the ones who think that could be seen in character if you squint a bit (it was reasonable to think Dean was simply dead, and by then it was quite clear how dangerous it was to reverse death), but are unable to accept his washing his hands of Kevin being Crowley's prisoner (particularly since he could have just let Garth know about it and gone on to whatever normal life he wanted) as anything approaching sense for the Sam we knew. And at the same time as this, he ''never'' acknowledges his own role in turning Benny into the monster he accused him of being, with the show acting like Dean was the only one at fault in that rift.

* Rowena. Is she a [[AffablyEvil charming]], [[EvilIsSexy sexy]] villain who brings some much-needed humility to Crowley and the Winchesters? Or is she a poorly-written, ham-handed attempt at "girl power" who's just as laughable as her schemes? The fact that her plans rely heavily on Crowley and other characters suddenly deciding to carry the IdiotBall doesn't exactly help with the latter interpretation.

* John Winchester: [[AbusiveParents Bastard!Daddy]] or Daddy Of The Year? There seems to be a growing consensus among fans (at least on tumblr) that he was an awful human being who abused and neglected his children and pretty much ruined their lives, regardless of how good his intentions might've been. However, other fans remain adamant that John was, if not the best father, a three-dimensional character and a flawed human being who still loved Sam and Dean and really did do his best by them. Even the cast and crew seem divided, with Creator/JensenAckles [[spoiler:wanting him back on the show]] and Creator/JaredPadalecki thinking he was a bad parent. Funny, considering their characters' views on the subject. Jeffrey Dean Morgan himself was frustrated by his character's behavior, but ultimately defended him against criticism and said that John did love his kids.
