There is NO excuse for raping a child or anyone for that matter. However, it has been proven that viewing some types of porn helps satisfy urges that would otherwise be directed toward actual violence. Japan, for example, has a lot of legal (presumably simulated) rape porn and their sexual crime rate is WAY lower than any western country. If you don't give people an outlet, they will find one on their own. This is often a real violent act which, we can both firmly agree, is not even vaguely acceptable.
