it's not really a catholic thing as it is a cult thing that involves a infestation across all religions - tho in catholcism's case it has a heirechy in the pope so it is sort of at the top. And much worse at the top than just engaging in sacrifice and murder of kids as they are responsible for wanton slavery across entire countries with the help of the Queen - but that's a long story.
Long story shorterโฆ. I think you made the right decision leaving but the religion itself isn't evil - nor are most people in it. It's the cult that uses institutions and there are very few if any that are free from their tentacles
