Most people everywhere are normal people at their core with empathy and a conscience. It was probably easier to rationalize or suppress the fact that you live in a genocidal ethnostate before October 7th.

Also even if someone is groomed into being a hateful, cruel, genocidal piece of shit there's still a line between cheering for that and actually being confronted with what it materially means that fucks people up. For every true psychopath who genuinely revels in the harm both external and internal, you've probably got at least as many getting all sorts of permanent wounds inside while trying to live up to the ideals of callous cruelty they've been taught or getting swept along in a sadistic frenzy. Fascist ideology lionizes that self-destruction as a sacrifice made on behalf of others, but just saying "it's good to hurt other people, and also yourself" doesn't actually work to blunt the consequences so much as it does simply lead its footsoldiers to destroy themselves further enacting violence on behalf of their rulers' whims.

And this principle doesn't exonerate a thing, of course, it just highlights how even in the most cynical and self-serving contexts genocidal hate and cruelty is also extremely self-destructive. It's not only an abomination that brands someone as ontologically evil, it's also bad for them too. Literally no one wins but the most distant and cynical ghouls who can reap the material benefits without having to reckon with the consequences.
