Lol the Satan she worships (because it's not like CoS where it's "atheistic satanism") to make mommy and daddy mad (ie the Christian one) is literally the embodiment of evil and negative emotion like envy, hubris, *cough* narcissism*cough* Yeah no, your Satan relishes in death, destruction, and misery. Sacrificed cats, dogs, goats, humans, he loves all of them as long as they're dead and their blood was spilled for him or out of hatred.
Because remember in Jewish and Christian texts, lambs would be slaughtered in sacrifice to God to cover sin. So of course, when Lucifer tried to usurp God, he'd want humans to slaughter animals for him. Bitch can't even worship her own Satan right.
