horror Sans looks pretty much bored with everything. He seems to be perfectly fine with killing humans, however he appears to avoid eating humans himself. Even going so far as to have notes to Papyrus stating to stop him if he ever tries to eat anything moving (humans, he outright specifies). He also hints in previous pages of the comic at his avoidance of human meat.  Like the original sans, he cares for his brother deeply & still sleeps at his sentry station. He also enjoys making head dogs (hot dogs made from severed heads). His jokes and pranks more scary and dangerous than being funny and annoying. He is known to enjoy more psychological torture, which is why Flowey warns Aliza of his traps. He has amnesia, (due to getting his skull broken) that he doesn't remember about Frisk.
