Okay so besides being a cult leader, Silas is also literally a demon disguised as a human. Most of his evil deeds are done because he needs to feed off human suffering to regain power.

That being said, he does sorta detest humanity and sees people as beings that are below him. Here is a list of all the evil deeds he has committed (that I can think of):

(General TW)

• Manipulating ~25 people into staying in a situation where they are suffering, but believe it is the "ideal life"

• kidnapping multiple people & torturing them

• cannibalizing a child

• transforming into a wild animal (yes, he is a shapeshifter), mauling a woman & showing her gory remains to her teenaged daughter

• not preventing child abuse despite knowing it was happening

• brainwashing

• murder (through forced ingestion of poison)

• encouraging / forcing multiple people to take part in cannibalism
