Hatred we can manage. The tension of human nerves during noise, danger, and fatigue, makes them prone to any violent emotion and it is only a question of guiding this susceptibility into the right channels. If conscience resists, muddle him. Let him say that he feels hatred not on his own behalf but on that of the women and children, and that a Christian is told to forgive his own, not other people's enemies. In other words let him consider himself sufficiently identified with the women and children to feel hatred on their behalf, but not sufficiently identified to regard their enemies as his own and therefore proper objects of forgiveness.


But hatred is best combined with Fear. Cowardice, alone of all the vices, is purely painful—horrible to anticipate, horrible to feel, horrible to remember; Hatred has its pleasures. It is therefore often the compensation by which a frightened man reimburses himself for the miseries of Fear. The more he fears, the more he will hate. And Hatred is also a great anodyne for shame. To make a deep wound in his charity, you should therefore first defeat his courage.

C.S. Lewis-The Screwtape Letters

In the times where fear runs rampant, and courage runs the gauntlet; hatred becomes the sustenance of cowards.  To face fear with courage creates the ability to love.  Facing fear with cowardice spawns the debauchery of malice.   

If the manipulation of other people for the sake of control  becomes a means to success; exploiting fear by inciting hatred tastes not only palatable but delectable.  The bitter flavor of rancor is an acquired savor, but once a tongue becomes accustomed to it, a ravenous hunger for hatred consumes without remorse or regret.
