Wow... been a long time since I felt that genuinely disgusted by a scene. Like of all the twisted crap, was that really neccessary? It is just shock value. The Hero was clearly a prick already, there really wasnt a need to do that.
I loathe this kind of stuff normally but it can be used well if the writer has a good grasp of the gravity of it and folds it into the story with careful intent. This was just heinous and pointless.
Dropping the series I guess, or at least taking a break from it. But if they do this now, I will warn you all the author WILL do it again with one of the main girls. Because once a story crosses that line, the stakes have escalated to the point where tha author has no choice but to resort back to it for the story to have continued credibility.
