Re: The Joker's background?
Fantastic theory. But im not so sure if Joker was the one who did it to himself. It's a high possibility. And ive thought about that before. But it could also be at the hands of somebody else. Maybe his father, maybe a gangster, maybe he was abused and this was done to him at some point. Isolation (which parallels Heath finding a way to isolate himself in a hotel room to get into the mindset). So yes, isolation and abuse for any number of years could have made Joker lose all faith in humanity.
The gangster route always sounds cliché to me. I don't like it. So I think it was himself, his father or some stranger in general that did this to him. But not some gangster who carves his face up for money or whatever.
Id say his father is a big part of his evolution. And there's a woman involved too. Of course I don't believe the literal stories Joker tells about these two people...the details are not fact IMO. But there's a reason why this woman and father enter his stories. It's partly a call for help (subconsciously maybe, if he comes up with these stories on the spot) but without actually telling his victim his past with them.
The mystery is what im attracted to the most. I don't ever want to know what really happened, and nobody has that answer either. The only person that may have came up with something definitive for a backstory would have been Heath Ledger. And in a haunting way, that's another reason why we'll never know.
I see him almost as the devil. A lost demonic soul who just IS. He comes into the story like a ghost and exits the story the same way. And I don't mean when they capture him, throwing him in Arkham Asylum. Im referring to the TDKR novelization where there's a possibility that he has vanished from the institute. Which is what I choose to think happens. Never to be found again.
RIP to TDK Trilogy (2005-2012) but now let's bring on the Batfleck!
