7. Craig Boone (New Vegas)
Craig Boone is a hired sharpshooter working the night-shift in the town of Novac, and was troubled by the disappearance of his wife, Carla, until he found out that she had been sold into the Legion slave trade, and decided to kill her with his own rifle to spare her the horror of that sort of life. Since then, Boone became suicidal, though still expresses a strong deference to the New California Republic, turning against the Courier if he decides to strike against them. His various endings include death, re-enlisting in the NCR, working as a security guard, taking on the Legion as a one-man army, becoming a mercenary, and finally, being driven insane by grief, embarking on a suicide mission against the Legate. In F4, perhaps Boone has remarried and started a family; it'd be nice to see him move on after everything horrible that happened to him.
