I've always had a penchant for writing "woobie"(no idea if that's a proper name for them, but you know, those beaten-down, underdog characters you just have to feel sorry for) characters. However, until recently I've only really done very short stories of my own and a little fanfiction. I'm well aware that in the course of a longer novel, those characters will get annoying if they're there JUST to pull on your heartstrings. So my question is, what are some good ways to develop a character who starts out in the story as pretty pathetic(through no fault of his own), without just throwing that sympathy out the window and trying to make them an OOC badass or something like that? Cause that's not what I'm going for. Suggestions?
