It's all correct.

They killed him cause he told them to love each other. That'll get you killed just about anywhere. Humans love to hate.

That said the air of 'I'm special' didn't help.

They didn't barely kill him. He was dead for like a weekend. They killed the witches properly.

Except for the Sanderson sisters. They took a couple tries.

It wasn't his followers that killed him though. His followers did however torture and kill women.

They killed him because he pissed off the State, not because magic tricks.

Theres a film about the book about it.

They killed him on a fancier stake, too!
