Some people say that they shouldn’t have watched it event o review it, I think that it is not the act of watching evil that makes someone evil, but the act of acting upon it.
It is the same sorta argument people were giving last week why they should take down the ISIS video of the mad they burned in a cage. It is a “see no evil” approach that leads people to be Naive about Evil itself.
One has to confront evil and walk away unscathed (ie lions den and daniel).
