Cruelty is easy, and it breeds only misery. Kindness is harder, and you have to be brave to give it. To be cruel, you can stay closed off from everyone, wear a mask, but to be kind, in essence, to show love, you have to make yourself vulnerable, show your true self to someone and open yourself up to rejection.
Very little of the great cruelty shown by men can really be attributed to cruel instinct. Most of it comes from thoughtlessness or inherited habit.The roots of cruelty, therefore, are not so much strong as widespread.But the time must come when inhumanity protected by custom and thoughtlessness will succumb before humanity championed by thought.
