Michael: thanks for writing this.

"Choosing hope" over revenge is the best lens to view the Boston Marathon bombing.

Seth Godin suggested a similar world view for Superman in http://sethgodin.typepad.com/seths_blog/2012/07/superman-batman-and-worldviews.html

Superman comes to our world with his gifts and sees his life as an opportunity and an obligation, one that he embraces. Superman could easily kill all the bad guys in a heartbeat, but he never does. For him, every challenge is an opportunity for healing. He believes in redemption and finds pleasure in using his gifts to help others.
