Lol, I can agree with some things there but if you want it to be realistic you wouldn't be able to fight much after being raped, so a debuff might be in order. Instead of fighting them you would have to run away until they give up and then you can go find some new weapons and take revenge. x)
The reason I wanted the essential function is because it gets annoying when one of his companions deal the killing blow while the rapist prepares himself. You could make it optional with a config menu or alternative esp.
