Which brings up another question, if you are a paradox, and killed your self, wouldn't you already be dead? Can you kill what is already dead?

No as from the moment your past self is dead, you destroy any connection between you and the past self. As I said you are a being with no traceable history who while you have no cause is still alive and still exists. Your actions don't erase your existence only your history. So it is still possible to kill yourself or have someone kill you, you still exist and are still alive.
