It’s all really simple, kindness is good, cruelty is the greatest sin possible – now, as we naturally are kind; the question is, what causes cruelty? and the answer is, firstly, though we are naturally compassionate, we are also naturally egotistical; hence, when our ego feels slighted, we God-forbid become cruel; though to overcome our compassion side, we justify our evil through rationalizing that the other person deserves it – hence the antidote is to get rid of our ego, which comes about, through realizing, a. Everything is only God, and b. Our only purpose of existence is to be kind!
