John Hobbins has a great post on the tragedy here: http://ancienthebrewpoetry.typepad.com/ancient_hebrew_poetry/2012/07/why-did-james-holmes-do-it.html
I thought this dialogue from the last Batman is fitting for all of those seeking to blame his actions upon conditions external to his own self exaltation.

bandit. So, we went looking for the stones. But in six months, we never
met anybody who traded with him. One day, I saw a child playing with a
ruby the size of a tangerine. The bandit had been throwing them away.
