Sorry for your loss. Vibes.
To be honesty, I generally dislike people like this. No disrespect, but on the whole, a disregard for social limitations irks me. I don't mean to say that he wasn't a good man, though.
I would say keep writing. I'd love to hear his story, especially coming from a friend of his. Definitely try to dissect his psychology and discover why he lived like he did. Stories of psychology can be beautiful, tragic, even enlightening, but are always interesting.
If anything, that would be a good way to honor him.
