I think also there's this beautiful element where he just- gave up. Evil was the winning side and he was so tired of losing. Tired of being hungry and afraid and powerless. Tired of not being able to protect his family or feel proud of himself. He also surrendered to the vision of humanity Gaul was pushing by very effectively grooming a young person.
It was what it always is with people - a combination of choices and relationships and society.
And then, once he'd crossed certain lines, he kept doubling down every time what was left of his conscience twinged. I truly think the propaganda about how the things he does are necessary for "peace" and he's "Panem's #1 Peacekeeper" are lies he's telling himself as much as everyone else.
That's a far more useful moral narrative than "crazy people ruin everything with their in-born evil" or "Lucy Gray was a cautionary tale."
A lot of people don't want to hear what the real cautionary tale (teen Coriolanus) is saying because it's too real and human. Once fascists have all the food and safety and power, many people will mutilate themselves for that, bend themselves to fit the mold, and justify it even if what's left of their heart haunts them. Once they have all that power, even many people with consciences will crumple.
It's awkward rn in the US, since we seem to be teetering on the edge of an abyss.
But that's what it is. Lying and being ableist instead of giving the art a fair hearing won't change it.
We also have Haymitch, who is truly broken and complicated and even complicit (under duress) for decades- but he survives and remembers and keeps enough of his heart alive to see and help create the end.
Many people alive now will possibly have to endure like that. And even if they crawl into a bottle like he did or lose their minds like Peeta and Katniss, they can still see the dawn of a better day. It's not the end, to be broken and tainted. It doesn't have to be the end. It doesn't make someone evil. And many people alive right now who didn't have to will die like his friends and allies died, senselessly.
It's not a promise of easy victory. It's not a promise that evil is easy to spot and resist. It's better than that, it's truthful.
I keep thinking of this quote from the BTVS episode "Lie to Me":
BUFFY: It'd be simpler if I could just hate him. I think he wanted me to. I think it made it easier for him to be the villain of the piece. Really he was just scared.
GILES: Yes, I suppose he was.
BUFFY: Nothing's ever simple anymore. I'm constantly trying to work it out. Who to love or hate. Who to trust. It's just, like, the more I know, the more confused I get.
GILES: I believe that's called growing up.
BUFFY: I'd like to stop then, okay?
GILES: I know the feeling.
BUFFY: Does it ever get easy?
BUFFY: Yeah. Does it get easy?
GILES: What do you want me to say?
GILES: Yes, it's terribly simple. The good guys are always stalwart and true, the bad guys are easily distinguished by their pointy horns or black hats, and, uh, we always defeat them and save the day. No one ever dies, and everybody lives happily ever after.
Collins doesn't lie to her audience. I respect that and it means a lot to me to have her art at this moment. But it also makes it incredibly frustrating how much people wish she'd lie to them and tell them the lies like Giles tells in that quote. And how mean they are about that.
