No, it is never OK to emotionally abuse people.
It is also never OK to physically abuse people - ie, rape, torture, murder, assault.
But, by saying that emotionally abusive people deserve to be raped is like a child saying:
\"Mommy, she called me a loser and a nerd so I splattered her brains all over the carpet with my 9mm.\"
2 wrongs don\'t make a right, especially when one wrong is more heinous than another -
Everyone has gone through hurt and pain in relationships at the expense of a partner (man or woman) - that is part of life. Regrouping, moving on and learning never to get near a person like that ever again is also a part of life.
Rape can cause an unwanted child, a incurable disease or death.
An eye for an eye, or in this case, a whole entire head for an eye, is counterproductive to the whole \"moving on and learning\" concept.
