You have a choice whether or not to get up in the morning. You have a choice whether or not to go to work. And you have a choice to abide by the law or to break it. This is what it comes down to. Even though a movie might have controversial issues and happenings, you still have a choice on how you take them.
Most normal people can watch an explicit movie and take it only as an act of fiction.
While there are the few who fantasizing on being the person in the movie with no recollection or understanding of the consequences of their fantasized actions. I think not. The moral of the story is that no one is accountable for the actions of another individual. Accountability is a key role in our society. If everyone would take responsibility for what they have done then the world would be a much better place.
