I think the animation helps divorce the violence from reality. The sex certainly doesn't look all that realistic. I think the fact that it's animated, we get some leeway because of that.
In actions of enthusiasm, this drawback appears: but in those lower activities, which have no higher aim than to make us more comfortable and more cowardly, in actions of cunning, actions that steal and lie, actions that divorce the speculative from the practical faculty, and put a ban on reason and sentiment, there is nothing else but drawback and negation.
