Murder For Pleasure
-Humans are the only species who kill their own for pleasure. Other animals rarely kill their own kind, and if they do, it’s not for pleasure, but because they are protecting themselves or their family.
Risk For Pleasure
-Skydiving, base jumping, bungee jumping etc. are all examples of how humans put themselves in danger for pleasure; that rush of adrenaline. We are the only species that will stare death in the face for enjoyment.
Eating For Pleasure
-Humans eat to fill their basic need for hunger like every other species, but we also take it a step further. Many humans eat beyond their fill, way beyond. Gluttony is not practiced by any other species.
Hunting For Pleasure
-Killing just for the sake of killing is purely human. No other animal kills another species for the fun of it.
Consuming One’s Own Species For Pleasure
-Think of Ed Gein, one of the most famous cannibal-serial killers of all time. He ate humans for pleasure; yes, he enjoyed it. This is another trait which is unique to humans alone.
