Its not a games job to keep kids from doing that. Its parents. If a parent can't instill in their childs head that those things are wrong, it is not the games fault at all.

It is Mature for a reason. Kids aren't even suppose to be playing it. If they get a hold of it, it is not the games fault. Its the retailer who sold a child the game without IDing them, or the parents fault for buying their kid a game without being positive their child can handle the content.
