so vengefull and genocidal don't fall under the category of self-serving. christian God wasn't as nice as we know him today.
Satanism is in fact a legitimate religion if you actually look into it the thng is they consider the human self as their god, thus do not qualify as i've only drawn the conections with spiritual religions.
the followers of this ONE WAY (Jesus) have been killing each other for centuries over diferences intranslation and interpretation. i'm not sure this is what Jesus wanted when he said "love thy neighbour".
i'm not sure about human sacrifice(oh wait Jehova ordered that and then called it off.) but ritual orgie is a celebrationof the sexual gift and thus i chalk it up to different worship styles.
