Lost's main character Jack Shepard. Great character.
Always trying to save people. Always ended up killing himself.
His relationships with people are always beset with problems, because he rarely sees them as people, but as causes to champion or problems to solve.
Of particular interest is his relationship with his father. Never having the old man's approval, he turned that into a superhero complex.
Jack went to Phuket and got a tattoo from a clairvoyant Bai Ling. It read, "He who walks amongst us but is not one of us."
Jack will always be the hero from Lost. God, I love that character.
