Elseworlds: Batman #1

In a world where America is still part of a church-dominated England, Bruce Wayne survives the death of his parents in Gotham Towne. When Bruce comes of age, James Gordon tells Bruce that he suspects Joe Chill killed his parents under orders from the government. Bruce takes on the guise of the Batman to take his revenge for their murders. But he discovers that the conspiracy leads past Dr. Erdel's Green Man Project to a Star Chamber. Determining that the system was responsible for his parents’ deaths, Batman vows to carry on their quest to free people from oppressive religious rule.
