Books where all the bad guys get punished.

Reality/the world has me wrecked. Capitalism destroying the world, children are the biggest victims of the crimes of men, endless war, genocide, pedophiles aren't held accountable for their crimes.
I need a book where bad things happen and the bad people get punished accordingly. I don't need a happy story, but I want the victims to come out stronger and get righteous revenge.
