Sorry to hear this. I am glad that the movie gave him more widespread recognition in his final years. His stuff wasn't always my cup of tea, but I admired the fact that a guy like him (a Joe Blow) could make it as a writer.
"I like your Christ, I do not like your Christians. Your Christians are so unlike your Christ."
My two cents: I don't need to know more about Walter Kovacs/Rorschach. I know enough about him. I don't find him heroic, I find him rather detestable. So not focusing on his character/mental state/who he is and how he came to be? Fine with me.
