As cryptic and manic as Gal4's post is, it does have some wisdom.
We can't assume that people are mindless robots. Regardless of whether the law allows, the victims knows it, whatever, if you do something basically immoral, then there are going to be consequences. If not from the law, then from the victim. If not from the victim, then from your own self.
Any other method of thought makes us psychotic. Besides, fantasies are way more fun. You can have flying elephants in fantasies!
