Oh, I get it. Rapists want to be raped, murderers want to be murdered, wife beaters want their wife to beat them, etc.
What? No.
Self destructive behavior
can and does externalize.
Rapists often HAVE BEEN raped. Murderers often have BEEN WITNESS TO HORRIBLE VIOLENCE. Wife beaters almost always GREW UP IN A HOUSE WITH A VIOLENT PERSON, USUALLY A WIFE BEATER.
Cutters, suicidal people, passive aggressive people etc. can and have snapped and done horrible things to others after spending years doing horrible things to themselves. They often do it knowing that they'll die in the process, too.
"Suicide by cop" is pretty damned common.
Most of the biggest monsters in history wrestled with "Temptations of the flesh".
Most bad people who do bad things already pretty much hate themselves.
The "Golden Rule" doesn't account for this.
A suicide bomber's opinion of the golden rule is "I want to die, and I'm gonna share it out with everyone else." - They haven't broken the golden rule.
