Ahhh, the good'ol kill an unborn child ritual bonding experience, my favourite of the bunch.
It doesn't make it a murder club you're right, but it stems from one and what you are describing isn't really a religion if it's based on atheism.
I think believing in the Church even after stuff that has happened in the past makes more sense than edgy self worship, the religion isn't the reason bad things happened it is mostly all good and has taught good.
