I imagine if I were suddenly facing a potential 35 years in prison, I'd be at a pretty high risk of becoming depressed.
You're blaming Aaron for taking the supposedly cowardly approach and hurting his friends and family in the process, but what about the people who put him in this position? Are they beyond reproach? What about the people who affected those people? Clearly something fucked up along the way because I don't think Aaron deserved to be in a position where he had to do this because he downloaded bytes from a website.
Someone described the process in which a depressed person takes his/her life with a person standing in the window of a burning building choosing between burning to death and jumping to death. It can basically be the very same thing.
And to a certain degree, jumping just makes your problems disappear - just like that. But saying that the person jumping is selfish because he/she didn't contemplate the consequences? Do you honestly believe that killing yourself is something that people take lightly? That it didn't occur to them that they would be missed? Think. That point of view makes me sick and expressing it makes you extremely selfish in my eyes.
Edit : Also as Udo points out lets stop this line of argument for a bit. Some members of the community either knew Aaron or were affected by his work, lets not subject them to this argument right now.
I don't think anyone disputes that Aaron was probably not in the best of mental health to be facing this kind of thing in the first place, but even for a paragon of stability, a multi-year witchhunt and prosecution by the feds will push you to the limit. I know of a few people who have been in the eye AUSA doom (and some ongoing, like Harborside Health Center), and especially for an individual defendant vs. a group, it's very hard.
