Natural selection does select for traits that do not kill you while simultaneously selecting for traits that's promote fecundity. Those with traits that don't kill them survive. Those with adaptive traits that allowing something to thrive are also selected for through reproductive advantages.

I'm saying it's not selected for. If it were we would not be such a socially dependent species. Does it work, of course but it is not evolutionary beneficial to our species. Forced mating and aggression works but does not enhance a species in most cases. Survival of the fittest does not simply mean who can…

Usually stemming from unresolved childhood problems or trauma or chemical imbalance. It's not natural (aka, evolutionary beneficial) for a human to intentionally harm another human.
