I'm not saying I want to forget it all. Just some stuff. Stuff that defies the word "bad". That laughs at the word "bad" and sends it running home to mommy in tears.
For instance. Once I had to put a bullet through a newborn's skull because it was a vessel for an ancient evil that would destroy the world. I see that moment in freeze-frame every single time I close my eyes. At night, when all the lights are off and I'm alone in bed I can still hear the crying right before I pulled the trigger. Every time I see a baby carriage I have to grit my teeth and force myself not to scream and laugh at the insanity of it all.
Given the chance? I could do without that particular memory.
