Of all the times Joker has gone from the brink of extinction and surving things that would kill most (but that goes for everybody but 9/10 dosent really have the means to survive whatever it is he survived), do you think that The Joker is just an alias taken under people who started as either small or big time criminals and psychopaths that were brinked to a point of no return instanity (some argue that Joker isn't insane at all, just really weird yet genious compared to most of us and everyday people.)
