These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: The look of absolute horror on Percy's face after Coffey pushes the "disease" into his mouth, and the tear that rolls down his face just before he shoots Wharton could theoretically indicate that, rather than John forcing him to shoot Wharton, Coffey used the contact to show Percy everything Wharton had done. Percy, a small, sniveling, vicious, cowardly man was so broken by seeing true evil that he not only had to seek immediate retribution on Wharton, but spent the rest of his life catatonic from sorrow at just how evil the real bad guys could be. Look at his face during Del's execution. Can he not watch it because of how gruesome it is, or because he honestly didn't think it would be that bad and was having a My God, What Have I Done? moment?
Complete Monster: William "Wild Bill" Wharton is a Psychopathic Manchild awaiting execution at the Cold Mountain Penitentiary for murdering three people in an armed robbery, one of whom was a pregnant woman. When he first appears in the prison he manages to convince the guards he's in a drugged stupor, only to attempt to strangle Dean Stanton to death when his guard was down. Failing in that, Wild Bill contents himself with causing as much mischief as he can before his eventual execution. Eventually it comes to light that Wild Bill's worst known crime was the rape and murder of the two little girls that John Coffey is accused of killing. In order to stop the girls from calling for help, he told them that if one of them screams, it's her sister that he'd kill.
Whartondoesn't like just little girls... he also likes annoying jerkasses like Percy Wetmore.
Although it is ambiguous whether Wharton enjoys a real screw, or just a Mind Screw: his goal was not to have sex, but to watch Percy panic, and he's successful - Percy pisses himself in fear, much to Delacroix's amusement. Given one of the many nicknames for sadistic prison guards, one could say that Wharton enjoyed screwing with the screws.
Subverted with Delacroix, as, after all, there was a reason he was sentenced to the chair. But no doubt he regretted what he did, and how he died was, to say the least, excessive. Even if it qualified as Laser-Guided Karma; he was an arsonist and murderer, and burned to death in the chair. In the novel, one of the guards even comments that when other townspeople hear of the botched execution, instead of being horrified they'll all wish they'd been there to see it.
Del is slightly more Woobie-ish in the book. As well as the main event, King also describes the minutes before Del's execution. He hugs Brother Schuster, the priest, who agreed to pray with him in Cajun French. While Del cries throughout the prayer, he's also visibly comforted and by the end, feels that he's right with God. Despite the horrific crime he committed, Del is still (well, YMMV) one of the more likeable characters.
Paul, once the full impact of the epilogue kicks in.
Dean, getting strangled and everything. Then four months after the story takes place, he gets stabbed to death. He also has two kids who are going to spend the rest of their adolescence without a father.
A rare example of a Woobie prison warden, though he's more of an Iron Woobie: Hal Moores, who personally disarmed a prisoner with a shank, sees his wife become terminally ill. When Coffey heals his wife, he breaks down sobbing.
