Letting Evil People Go By

Are some people so misguided in their actions they can be called totally evil? And what happens to them when they die? There are people who live outside the law --and some inside--who appear to have given up on humanity, but what of people who mostly treat others badly, ruining lives partially or completely? Some prosecutors are gleeful to do that, right or wrong. Bosses too or anyone with power. I believe power corrupts either obviously, or hidden from sight, it still corrupts. Without freely-given feedback invited, there are no barriers to revenge, paranoia, or simply allowing anger to take over.
I always had rotten bosses until I arrived at my job in Center City Philly. Often the nastiest people were not actually supervisors, but they had tremendous power anyway. If you don't agree with their ideas, you may as well leave immediately.
After about 50 years of fighting with nasty people, I finally began to stay away from them. I'd see one coming up the aisle at work and turn around and walk the other way. One enraged woman called me on staying away from her. I don't remember what I said but I continued to give her wide berth. Sometimes--most times--I get a kick out of arguing. It had never occurred to me before older middle age that I didn't owe the world a fight with the nastiest person in the room. I had no lesson for a bad actor, nothing to teach that the person didn't already know and reject. The rest of earth's inhabitants could also stand up to her or him, not just me. Inevitably, the complainers clammed up when it was their time to voice their own grievances. People who don't speak up never seem to. Ever. They go along to get along. So evil just breezes by till it hits someone like me....but I no longer deal with them. I wish other people would realize that just because someone says a lie nicely, that doesn't make it true. Hurtful statements and out and out lies can be presented as fact. It's up to the listener to research the truth. I'm not doing it anymore and sadly, neither is the press. The alarm has rung. I wish everyone would wake up.
