You can feel empathy for him without agreeing with what he's doing, you just get why he does it.
The guy is kind from the basis, he wants to be. But life didn't want him to be, his passed is terribly shocking. Plus if you notice, he doesn't hurt people who are kind to him and children are so pure that he doesn't do anything wrong in front of them, or it makes him stop. ''I did it because they were awful'' shows how simple and true to him is action is. He just tells the truth.
And at the end, he's really getting what he always wanted but in the ''wrong way''.
He's got a crowd that loves him, cheer him and like what he does.
There's so much nuance in his development it's incredible. The guy just can't contain his emotion, his dance is his way to get his feeling out. It's the way he's reacting to his action. It's so much more deep than any of the comic book interpretation. The way he's acting in the end is unbelievably human. He's just completely disconnected with our world. And I like how people are cheering him but he doesn't give a **** about their political opinion, he just wants to be loved.
And ''Life is a comedy'' takes so much more sens, for him, a young boy getting hit by a drunk driver is a joke, because ''That's Life''.
I also think it's a great criticism of our contemporary quest of being liked and always looking for approbation. (social media)
You can so much analyse about him dancing in a psychological point of view. You can see it as some form of narcissism, of self-esteem or just the way his body lives with his feeling.
This movie guys, is more than a comic book movie, or a movie about Joker. It's more than that, it's a true human tragedy, he's crying for **** sakes at the end. And when he's joker, he's the same guy, he doesn't try to act crazy or to act like a psychopath, he is just at the bottom, but it's where he feels alive.
And his joke ''I hope my death makes more cents than my life'' really has a great profound meaning. The ways he looks at it at the end, before going full angry, really show how he decides that no one will laugh at him anymore. He won't take it and he won't do what he's been planning to do since he had a gun.
I'm not on his side but I'm not on the society's side either, but we get why he's there. This movie really is a masterpiece and really goes where not a lot of movie went.
It is more than an adaption of a comic book character movie, it's a movie point. And a great ****ing one.
