“Immorality, no less than morality, has at all times found support in religion.”

Simplified Meaning:

Throughout history, people have often justified both good and bad actions using religion. Sometimes, individuals or groups claim their negative actions, like violence or discrimination, are backed by religious belief, just as often as positive actions, like helping others or being honest. For example, during the Crusades, some people believed they were doing God's work by waging war, and others truly sought peace and understanding in the name of their faith. This means that religion has been used to support both sides: doing what is morally right and what is morally wrong. It's important to see how religion influences actions and to question when someone justifies harmful behavior in its name. By doing so, one can think independently and make ethical choices instead of blindly following harmful practices labeled as religious.
