The Dark Knight - Chaos that Leads to Terror

Although not a "Halloween" movie, this week we explore a "dark" and scary movie, The Dark Knight. Heath Ledger won the academy award for portraying the total chaos and terror that is brought to the screen in Joker. There is never an explanation as to "why" he does what he does or "how" he has become this villain. The view is simply left with chaos that leads to terror. We see this in the world today - how do we deal with it? How can we contend with such unexplained violence?
