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: We have The Sociopath and SadistMalevolent Masked Man Machine. Machine takes part in snuff films to feed his depraved appetites and he is the one who rapes and murders an innocent woman on camera. When the tape is investigated, Machine is willing to kill more people, and commit more rapes on camera. When he attempts to murder the hero, he even gleefully whispers while strangling him how hard he's getting from the violence. Machine has no Freudian Excuse or reasoning for his action and he serves to show how a monster can come in the most innocuous of guises, particularly when you see under the mask Machine is a bald, chubby, harmless looking man named George who asks "were you expecting a monster?"
