You can’t hate anyone because of their race. You can’t hate anyone because of their religion. Yet if someone is evil, you can hate them with a vengeance. Is hating evil people the last human prejudice?
(FYI I am not saying evil people shouldn’t be rehabilitated, or if that is not possible, locked away for good.)
Thank you in advance to all who reply

Well, I think whether or not you hate someone often has to do with religion. Christians, as far as I know, aren’t really supposed to have hatred in their hearts for anyone—which is different from disliking (or being unfond of) them.
Now, I wouldn’t say that hating evil people is predjudice necessarily, because generally, unlike race or sexual preference or something along that vein, whether or not someone is good or evil is determined by their freely-willed choices. Meaning, we say that a person is evil because they chose to do evil deeds. So, the judgement isn’t necessarily “prejudice,” because it’s based on the merit that person chose to establish for themselves.
On a personal level, I would say that harboring hate for “evil” individuals is general human failing. It’s almost as if when someone does something extraordinarily heinous, they become a convenient whipping boy for us—taking the focus off of our own faults.
“Well, I know I shouldn’t have cheated on my wife, or stolen from work, but at least I didn’t kill people—I’m not evil.”
I’m not saying that we should find someone’s evil deeds contemptable or that we should seek due course of justice, but harboring hate inside just kind of rots the soul a little bit, no?
