A third reason why we should love our enemies is that love is the only force capable of transforming an enemy into a friend. We never get rid of an enemy by meeting hate with hate; we get rid of an enemy by getting rid of enmity. By its very nature, hate destroys and tears down; by its very nature, love creates and builds up. Love transforms with redemptive power.
Martin Luther King, Jr.There's another reason why you should love your enemies, and that is because hate distorts the personality of the hater. We usually think of what hate does for the individual hated or the individuals hated or the groups hated. But it is even more tragic, it is even more ruinous and injurious to the individual who hates. [...] For the person who hates, the true becomes false and the false becomes true. That's what hate does.
Martin Luther King, Jr.
