"a person who commits a series of murders, often with no apparent motive and typically following a characteristic, predictable behaviour pattern." sounds accurate
Then how about those hugeass prehistoric mushroom things that existed before trees? Surely our ancestors lack the brain cells in being able to cut those things down (or even comprehend them).
Something else that further reinforces your pre-conceived notion that mankind is just a series of disgusting murderers and not a culture that has adapted to the necessities of the world it lives on over the centuries?
Nah, just a musing. We're not all ruthless murderers, although, we also didn't need to kill so many things but we did so anyway because that's what we do. Try telling me that we really needed to kill sharks for their fins and what not because it was a necessity for man-kind xp
Whateves, I got my point across.
