in that ask you mentioned other villains in your stories having similarly “tempting mistakes” — what are some other examples of that, in aurora or elsewhere? i’ve always been really interested in the characterizations of your antagonists, and i’m wondering if this has something to do with it
The Collector is so fixated on solving a problem that she's completely divorced herself from the world around her, and will disregard any cost in lives or suffering because it is truly irrelevant in the paradigm she's anchored herself into. Hyperfixation is a bitch, and obsession can make anything outside of it seem unimportant. To create a character capable of such effortless widespread suffering, she needed to be truly incapable of seeing it as relevant. Jolon is the same way, but in a much smaller scale.
Tahraim is a similar model of "disregards everything beyond extremely narrow priorities of what he cares about" but he's much less of a dick about it, so while he's not really a villain, his morality is still pretty situational.
Zuurith, like Shrike, is obsessed with control. He's the epitome of "the world would be perfect if everyone just did what I think is right," and that paternalistic impulse feeds into every savior complex and vigilantism fantasy. He wants the world to work Just So, but he can't even make his own domain do that, and rather than seeing that as a failure of the goal itself, he sees it as a failure of his execution.
Tynan just wants attention. Terror is the easiest way to get it. He's the star; he's the coolest, deadliest thing around. He's unstoppable, a literal force of nature. And yet he still only has so much control over how he's perceived, and that makes him so angry.
The Void Dragon is self-awarely evil. He is a monster, a nightmare, the dark heart of this tomb world. He knows what he is, and that makes everything so easy, because he's not capable of kindness or mercy or creation or anything beyond his role as the eater of stars. He knows what he wants, and he knows how to get it, and the only joy in his existence is how much he gets to play with his food. When you're trapped and the world feels small, cruelty is very, very easy. When you're certain you're only good for hurting things, hurting things can become all you do.
The Paladin Champion knows he's right. He has built everything around the rock-solid understanding of what is Good and what is Evil, and because of the cause he serves, what he does is Good, even if it is at times cruel or imperfect. Being certain you're right is a very dangerous thing. Being certain of the morality of your cause can make it very tempting to stop listening to the morality in your head.
