Are you asserting that suicide is the most reasonable option in a situation like this?
I've noticed this sentiment a lot lately (you hear it all the time in discussions about youths who commit suicide after having been bullied excessively); as if outside forces are overwhelmingly responsible for when a person takes their own life, and any personal culpability that that person might have had is thrown out the window.
I'm not saying that the events that contribute towards a suicide should be ignored, but it's important to remember that suicide, by definition, is always a personal choice. We should be doing more to assist, or even empower, those who feel as if they have to make that choice.
Instead of doing the easy thing and blaming a scapegoat (to say that "[Aaron] was practically murdered by the state" is ludicrous, and not at all productive), why don't we look at the root of the problem - what really caused Swartz to do what he did (i.e., a poor state of mental health, something that currently affects millions of Americans) - and work towards preventing it from happening to others?
