The Emergency Exit

//Note// this is a concept, not actual cannon, I've just got an idea for an origin about the Joker:)

The man is alone. He walks through the street, listening to music through his earphones, his head hanging as the rain drenches him from top to bottom, completely and utterly alone, there are people around him, but they aren't there, not to him. His mind wonders to dark places, taking him through every dark thought he'd ever had, 'no!' He thinks, and he pushes the thoughts out of his head.
For now.

Jye Reeves is a man who is desperately trying to hold on to the good in the world, and bring happiness to it, but the world resists his attempts to help, and instead pushes him out, he is pushed and pushed until he can barely stand, finally one question remains...
What breaks a man?
