I’d suggest considering empathy once you get past the anger, their former selves would be equally repulsed by their behavior, and for many I expect their current selves feel similarly despite their lack of control. The villains here aren’t the broken people.

The villains are the people who let these people continue to commit crimes and make life worse for others in the name of empathy instead of quickly and forcefully moving them into compassionate care where they have any chance of recovering and joining the vast majority as contributors to society.

The villains are those of us who tolerate this kind of behavior in the name of compassion.
