Hi love! If you're still doing the choose violence ask game - how about number one? Any fandom of your choice :)
And potentially niche answer, but John Twist. Jack Twist's father from Brokeback Mountain.
There's a tendency to paint him as just flatly a hateful asshole, and I understand how people get there, but that's such a gross oversimplification. I'm never gonna say John is actually a nice sweet guy, but like there's nuance to be had here.
(Uhhh cw for discussions of normalized violence against children to follow.)
We don't see a lot of John in canon--both the movie and the original novella, he's in one sequence (technically it's two scenes, but most people are gonna think of it as one scene and that's reasonable). And what we see of him, he's Not Nice.
In this sequence, Ennis has gone to visit Jack's parents after Jack's death to offer to take Jack's ashes and scatter them on Brokeback Mountain as Jack had expressed he wanted. John refuses, rebuffs Ennis, aaaaaand makes some comments that are basically an indirect but scathing "I know what you and Jack were."
He's undeniably a cantankerous asshole about it, so between that and the fact that earlier in the book Jack tells that John was unsupportive of Jack's rodeo career and Jack does recount having been beaten as a punishment by his father one time when he was a child, I definitely understand how people land at a place of "John is just all around terrible."
But.....there's some reading around what we're directly told that people aren't doing.
Go with me here. We know that Jack is "not yet twenty" in the summer of 1963, which is generally taken to mean he's 19. That would have Jack born in 1944 or '43, depending on what time of year his birthday is. To be the father of a child that age, John was most likely born in the 1920s--he's Greatest Generation. He lived through the Great Depression and WWII, and was probably a soldier in WWII.
There is not an American man who came through those moments of history untraumatized, and very very few of them ever dealt with that trauma.
Of fuckin' course John's an asshole. Of course he was a kinda shit father. He's screwed up. That's par for the course for a man of his time.
I've seen some portrayals of John as just a relentless and merciless abuser that I don't think are warranted. Honestly, if John were like that, I don't think Jack would be the kind of person we're shown him to be--I think he'd be more like Ennis.
Jack doesn't describe John as having beaten him regularly his whole life or anything like that, he cites one particular instance. And I'm not saying that's okay, the instance in question clearly had a lasting effect on Jack, but fucked up as we know it to be, corporal punishment--especially for boys--was extremely normalized at the time. The one instance Jack mentions probably wasn't the only time John hit him, it's just the time that stands out as when he went too far. For John, that would most likely have just been part of what he thought he was supposed to do as a father, disciplining his son. And probably a place where his own trauma leaked through. And that's horrible, but it lacks the malice I often see attributed to him.
Then, when we do see John in canon, yeah he refuses to let Ennis take Jack's ashes, but the man is grieving his only son, I think he can be excused for digging his heels in about having Jack interred in the family plot. That's the one bit of control he has left in the situation, the one way he can still keep Jack safe. If I were grieving a loved one and some stranger showed up uninvited wanting to take away their earthly remains, yeah I think I'd be kind of a jerk about it too.
But for as much as John is unpleasant to Ennis, he doesn't kick him out. He doesn't object at all to his wife, Jack's mother, inviting Ennis in, offering him cake and coffee, letting Ennis go upstairs alone to Jack's room, and take with him his and Jack's shirts he finds there. The one thing he actually roadblocks is Ennis taking Jack away.
John Twist is an easy scapegoat for Brokeback fans' negative feelings about the homophobia and toxic masculinity that permeate the world the story takes place in, but the John we're actually shown is not a monster. He's damaged.
