According to Osho, animals are not violent or vicious; only humans are. Creatures may kill more than they eat through poor calculation, not for sport. Ants and mosquitoes simply follow their instinctive business, unaware of you. Violence requires cunning, memory and calculation—Machiavellian mind—unique to man. Animals living with humans can be 'corrupted,' appearing humanlike; if they seem to enjoy cruelty, they are near human birth.
Animals aren’t being mean; they just follow instincts, while only people plan and enjoy hurting.
