The man who rapes a woman and leaves in most cultures dooms her and her child. There is no one to protect her or her child from the dangers of the natural world. The offspring likely to survive are those where the male is available to defend, provide food, and assure participation in the group. R ape is incredibly destructive. In the modern world, rape victims suffer enormously.
Many rape victims suffer depression and memory loss.
Aberrant behavior is frequently associated with rape. Suicide among rape victims is extremely high. Children who were conceived in rape frequently experience poor acceptance at a minimum and violence at the maximum. To maintain that evolution favors the rape environment to a functional family environment in the producing of children is ludicrous. R apists are frequently people with severe psychological disorders themselves.
