Srebrenica massacre

In war situations, some people lose the one thing that makes them human: morality. Their actions are so unreal, it makes you think they are nothing but wild animals. The Anatomy of Evil is about confronting this heartlessness. Director Ove Nyholm decided to try and find an explanation for the horrendous behavior of perpetrators in Nazi Germany and in the Bosnian War, responsible for mass killings of defenseless victims. The result is a series of chilling confessions of soldiers with a dark past.
