Bad Samaritan

In the "Bad Samaritan",  we learned that David Cash was disliked for his actions and not intervening when a little girl who was being rapped and then killed by his friend. I was really shocked for I watched because again he didn't do anything and then walking out and didn't ask for help to stop his friend. Honestly  that's Fuc*** up! If I was in his shoes I would interfere because anyone's life is important especially a little innocent girl.
