But that's not the role he fills. Deadpool isn't "the one who curses." He does curse, yes, but that's not what he's there for, any more than Professor X being there as the bald one, or Hulk being the green one. It's an aspect of their character that adds flavour, not their defining role.
That's all I can think of, at any rate.
