Everyone is right. It’s depraved to normalize evil. And that includes the horrible people who’ve decided to be its avatars. It’s wrong to muss their hair and discuss how to work with them, as if there was something well-meaning about them.
Not recognizing them for what they are and not rejecting the endless harm they do is to lose your immune system. Cancers kill because the immune system is fooled into not fighting them. Social cancers work the same way.
There are interesting articles  turning up remembering normalization at work in the early Third Reich.
“The rough edges of the extreme anti-Semite and agitator of the masses were sanded away through the creation of a new, sophisticated persona that emerged in carefully crafted domestic surroundings. With silk curtains and porcelain vases, Hitler’s designers suggested an internal world that was both cultivated and peaceful.”
That kind of normalizing, which ignores the damage being done, is depraved.
But there’s another side to the issue.
Some of the anti-normalization outrage focuses on rejecting everything to do with people who do horrible things. You’re barely allowed to point out they had mothers once and were small and blew out the candles on their birthday cakes just like you and me. That’s also normalizing them.
It is, but it’s a very different sort of normalizing. It’s never all right to pretend the harm they do is okay. But it’s always necessary to recognize how widespread, how normal, the seeds of those horrors are in everyone. The seeds are just small. It’s easy not to see their potential. That’s why they can grow.
A writer with a pedophile father  talks about this.
We don’t really just condemn the sexualization of children. Instead, we condemn the very existence of child abuse altogether. It’s as if the crime includes being victimized by it, or responsible for bringing it into the light. We take an ontological roach spray to the whole event, either denying its status in reality altogether, or competing with one another to proclaim the most exquisite forms of torture for the perpetrators. I can’t count how many times I’ve seen the most strident liberal break character to loudly call for the prison rape of perpetrators.
That this darkness is actually woven into and throughout the fabric of our society—that these abusers are among us—is simply too much to bear. So the darkness is ignored except for the most distilled, theatrical, and viscerally repellent cases. …
Most of us would sooner discard all parties who have been tainted by this event than we would look at how tenuous the sanctity of children really is, how commonplace abuse is, or see the capacity for the mostly good to do periodic evil. We live in the same universe as those who abuse kids. We walk among them. If we want to end the sexual abuse of children, it will begin with the recognition that we are simply not that different from them.
If you assumed cancer cells are evil extraterrestrials otherwise unknown on earth, you could never find a cure. It’s when you know they’re ordinary cells with some processes running amok that you have any chance of stopping it.
Wholesale monsters who kill millions and retail ones who destroy a few women or children or men are not some kind of incomprehensible Others. They’re ordinary people who started running amok with appalling horrifying lethal consequences.
Never underestimate or normalize the malignancy. Never assume that normal people can’t become malignant.
Then we could at least try to stop the transformation at the source, every day.
That’s less fun than performing virtue by stoning the devil, but more useful.
