a very valid way to become immortal is to change yourself into something which is easy to make immortal. You just lose everything about yourself that death would have taken.

Death takes more from someone who hasn't changed themselves, at least partially, into something that can survive past it.

A vigilante is just a man lost in the scramble for his own gratification. He can be destroyed, or locked up. But if you make yourself more than just a man, if you devote yourself to an ideal, and if they can't stop you, then you become something else entirely...A legend, Mr. Wayne.
