Hey, I'm not held in the best regard here [killed back in 2013, haven't made a decent impact yet] but I know how it feels to be schizo and bipolar... Maybe if you had him refuse help and display that he likes being the way he is, and taking his emotions out on others [as Ultimate mentioned] it might go a little ways into changing how the character is perceived. I for one have often been given advice I didn't take, and this has led me to being kicked out of numerous feds and causing friends to walk away. It's led me to being a 'heel' in a way, I think you could make something happen in that vein. If you play any character the right way, even if they're based off others, you can make them unique and fit what you're looking for. Hope our advice helps you. Peace. ^__^
