This idea is silly, you don't have to worship anything at all to be a good person or an altruistic person. You don't have to worship any particular god to be a good person either. Altruistic behavior even exists in other species.

Religion has done a lot of good for the world but also a lot of bad, Christianity included. So many wars and suffering. Deliberate crimes. Subjugation of vast populations. Political intrigue. Religions are full of the same failings of the non-religious because they are inhabited by human beings. And at the end of the day it is not religion that has advanced the species but dealings outside of it. For a large part of recorded history, humanity has advanced in spite of religious institutions.
