I will always have a soft spot for this character, the joker. He comes off as this abusive type crazy person in comics and in films. But, if you look at this character from another angle, you will see that this character is very flawed, and broken. He has a past and has had some tough breaks in life.
The joker is like an outsider, and he knows it and doesn’t seem to mind. He chooses to live his life for himself and not for anyone else. If you think about it the joker can be in all of us. He represents what it means to be human in this crazy world.
