Because white men also have morals and standards. If another man decides to chimp out and act like a rapist nigger who can't control himself, then other morally superior men will react accordingly. No one forced that decision except the aggressor. You want to act subhuman? Then you get subhuman levels of empathy. Part of the reason white men got so far was their ability to not only see right from wrong, but not tolerate bullshit and put their fucking foot down to keep degenerates in their place.
