It's sad to have to realize that "good" (whatever that means) people can become nazis too, and it's almost like you have to mourn them before they die. But they have died, that person has allowed their hueristic to be replaced with an exterminationist one, and in doing so discarded what made them worthy of mourning in the first place. I had high school friends who became nqzis and tough shit, you have to write them off. Ironically, I look at fascists the way they portray rioters: as zombies. But where they see zombies as nothing but metatextual human meat targets, I focus on what they actually are, in the lore of all those stories. They're the final-stage victims of a brainworm infestation, their actions are dictated by a mindless hate fashioned by a mindlessly atavistic un-sapience. They have made themselves human cnidocytes, individual stinging cells in the body of the mad god Capital, and will go on stinging and poisoning forever until they're stopped. Hopefully whatever's left of the person they used to be in there can glean some measure of calm, perspective and understanding in the quiet moments after someone acts in defense of the rest of humanity, but thats's about the best you can realistically hope for them.
