My taste in heroes

I watched the episode of The West Wing this evening in which Josh is claiming to be OK, but is asked to speak with a therapist, as he's suffering from a psychological disorder brought on by being shot earlier in the season. I realized how much I like tortured heroes in general, and how I always love those episodes of any show in which they delve deeply into the the troubled psyche of characters. Usually this has to do with death. In "Walk The Line" and "Ray" I thought it was done cheaply. In the "chicken" episode of M*A*S*H*, in which Hawkeye is talking to a therapist, I liked it. I like tortured heroes. I don't know why.
