These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: This incarnation of Satan is nothing but pure evil. Every millennium he escapes from Hell in a bid to destroy the world by fathering The Antichrist and opening a portal to his own domain. He commits many atrocities over the course of the film for very little reason or just for fun. In his opening scene he possesses a New York businesman, makes out with his friend's wife in front of him, then blows up the crowded restaurant they were in. He later ditches the host when the body is close to death. He happily murders his minions and random strangers to blow off steam; crucifies a priest to a ceiling and later massacres a roomful of them; burns someone alive after the victim refused to kill his best friend; tries to rape the girl who was chosen to carry his offspring; and forces the hero Jericho Caine to relive the murder of his wife and child after he refuses to help the Devil in his plans.
Genius Bonus: One of the first things that Satan does upon arriving on Earth is to have a threesome with a mother and her daughter. This is something the Bible specifically mentions as a big no-no, so it's understandably something that the Devil would delight in doing.
Memetic Mutation: You'll usually see "I vuld like to talk to yew about Thomas A-qui-nas" and "You want to fuck with me?!..." on most Arnold soundboards. A lot of them also remove the "with" in the latter quote.
