I just started rereading Brubaker's Cap run and finished "The Lonesome Death of Jack Monroe". I'd forgotten how this story was a portrait of a man spinning out of control at the end of his life and then being put down with no real understanding of why it was happening. Really dark, depressing stuff. This also made me think of White Tiger meeting his end around the same time also under less than heroic circumstance. What are some other examples of heroes dying tragically in fairly mundane ways (by comic standards).
