Satan is the angel of pride, the most beautiful of all angels.
Note that pride is the deadliest of the 7 deadly sins, and is even said to be the root of the others.
Satanism is the worship of the self as god before God. Pride? Get it?
Appropriately, satanic imagery tends to surround pride culture. It's not coincidence, it's illuminati business.
Pride brings about delusion, uncharitableness, destructiveness, schism, heresy, all manner of evil.
Evil that pride itself even blinds people to the existence of.
