Nil magnum nisi bonum. No greatness without goodness. - Yann Martel

I'm afraid the popularity of the domestic cat would drop very quickly if little kitty could roar its displeasure.

Oncoming death is terrible enough, but worse still is oncoming death with time to spare, time in which all the happiness that was yours and all the happiness that might have been yours becomes clear to you. You see with utter lucidity all that you are losing.

It is simple and brutal: a person can get used to anything, even to killing.
