Some of these “enemies” dehumanise themselves very easily. Narcisistic sociopaths who actively and openly brag about manipulating “idiots”, saying they’re the best shit to ever grace the earth and downplay their crimes while laughing all the way to the bank to withdraw ill gotten gains? Yeah, real hard to believe they’d ever want to redeem themselves.
Couple that with the general feeling that rich assholes always get lightly punished whenever they’re caught and it’s even easier to understand the bloodlust for “proper punishment” against them.
