So, that was Nature's way. The mosquito felt pain and panic but the dragonfly knew nothing of cruelty. Humans would call it evil, the big dragonfly destroying the mosquito and ignoring the little insects suffering. Yet humans hated mosquitoes too, calling them vicious and bloodthirsty. All these words, words like 'evil' and 'vicious', they meant nothing to Nature. Yes, evil was a human invention.
