Huge amounts of blood, some gore, and very many horrific views of dead people either as rotted corpses or with severe wounds. Repeated flashback and some contemporary scenes of people being burned alive, with screaming.
Occasional gun violence, sometimes only brandishing, but people and demons are shot a few times, too.
One person acts in a hostile and aggresive way to their ex-spouse in a couple of episodes.
A woman is decapitated ( the process is not shown). Her dead body is seen lying near the chair, while her head is on it. The scene lasts a while. Graphic and gory
A witch vomits with blood and gory substance mixed with black liquid
