I don’t know why, but I have the feeling of guilt. I barely knew the guy, we were chatting about pneumatic endoskeletons a couple of times, I was on his server, and then he posts that one Twitter message. I was disgusted, terrified and feeling guilty that I didn’t manage to help him.

I will feel the same guilt for the rest of my life. I know he had done terrible things, but he still could get help.
