Maybe for the first half, but their character development diverges at the end. Travis Bickle attempted to do something good, however misplaced, but the joker just wanted to watch the world burn.

The way I see it, Travis thinks he’s doing something good, and succeeds in becoming a ‘hero’ purely by accident.

That’s the beauty of the movie. He steps past the breaking point but his focus was on getting the girl out so all the violence is justified. But he’s not perfect, otherwise his true intentions would have been completed and he’d be recognized as the monster he really is. It’s all perspectives.
