he also played a video game called KILLER INSTINCT where the object of the "game" was to repeatedly hit your opponent without them being able to stop you. these were called COMBOS which is also a type of snack or "treat" the killer enjoyed frequently.
one could say he refined his instincts to those of a killer and had a taste for brutality.
Lmao they see him playing tekkan and beating king "perp showed a pleasure in brutalising animals"
He got that killer groove in him.
lol
