Cap is a patriot, and has a strong moral code, but he's also a bit of an ideologue...as a parent, I want my child to make up his own mind about issues so, no.
Ben Grim has horrible self-esteem issues, so another no goes to him.
Reed Richards is intelligent, resourceful, and hardworking, but has trouble setting priorities (hence having to repair his relationship with Sue). No.
Dr Doom is intelligent, resourceful, hardworking, and strongly motivated by his own moral code. Too bad his moral code involves total world domination and meddling in black magic in order to rescue his mother from Hell. No.
Batman has WAY too much emotional baggage. Also glorifies vengeance rather than turning the other cheek. Aversion to killing is a plus, but no.
Superman is probably a good role model, although the whole Clark Kent persona tells me he may have some unresolved issues...
Iron man is an alcoholic, fascist, megalomaniacal womanizer. No.
The Hulk essentially glorifies undiluted rage and lashing out blindly at others. No.
The Punisher. Ummmmm...no.
Charles Xavier is intelligent, resourceful, hardworking, motivated, and compassionate. And mucks with people's minds. No.
Having said that, of the above characters the three who most closely articulate the traits I would admire in a role model are Richards, Supes, and Xavier.
Cap gets an honorable mention for the strength of his convictions.
