I read a piece a while back that included a lot of comments from people close to him. They said that the federal case against him severely demoralised him, because even if his punishment ended up being minor, it would be enough to basically destroy his ability to lobby/campaign for the issues he was passionate about, effectively destroying his career. He was also apparently someone who was quite uncomfortable with the limelight, and the case against him made him into the kind of public figure who can get no respite from the public gaze. I can't imagine how overwhelming that must've felt.
I've seen no evidence to suggest that Aaron Schwartz didn't take his own life. However, morally, I would agree that he was murdered.
This might just be non-vegan apologia, but I like to think that recognising the ethical merit in veganism is a step in the right direction, especially if you manage to not feel unhelpful levels of guilt about it (my ex's mom was annoying as hell, because she would cry if she ever thought about the fact that the meat she was eating used to be an animal. She felt so guilty about it that the cognitive dissonance caused her to reflexively avoid growth.)
I used to be irrationally somewhat anti-vegan, but now I am merely non-vegan. I'm not even vegetarian yet, but I am closer to that than I was a year ago. I'm not there yet, but I'm trying. It makes me uncomfortable to recognise the cognitive dissonance in me when I acknowledge that my current diet is not in line with my personal ethics. However, sitting with that discomfort is one of the ways in which I'm trying.
Along those same lines, give yourself space to grow. The fact that you recognise being non vegan as not saying good things about you is itself, a little good thing, in my opinion. It's not much, but that self awareness is definitely pointing you in the right direction.
