I imagine he thought he was in the right.
I imagine he thought the government was oppressive and restricting basic freedom, as he saw it.
I imagine he wanted to do something to stand up to a government that opposed basic freedom.
I understand that sort of feeling. Maybe not on the issue of Intellectual property, but on other topics, I do understand the feeling.
But if I were to feel that all bets were off, and my life was basically over because of what our government has become ... well ... I wouldn’t end it quietly in a little room by myself.
Just sayin’
I imagine also that he voted for Obama. Twice.
Adjust your imaginings to the thinking of a “progressive” that this guy was, and not a more typical hacker who’s more of an anarchist.
