He has seen so much death and destruction in Gotham, and with immortality, that would only continue indefinitely. He might start to question his own motives and methods.

They would age and die while he remained, which could lead to him isolating himself from the mortal world.
If Batman becomes Joker in fanfiction, Gotham would be in chaos. Batman is the symbol of justice and order, while Joker represents chaos and anarchy.
