Dear PaperrFace, this is just a character with those characteristics, like some murderers in movies. Well, this is a rapist, as harsh as that sounds.
Those who play characters like this don't have problems either. Often, and I include myself. Having characters like this and creating stories with them can help you express yourself about things you can't, or even cope with trauma. I'm not saying that's the case for Headlocker, but maybe he does it out of a healthy taste for stories like this, and that's it..
