C.S. Lewis’ Screwtape on not relying on feelings of hatred:

In his anguish, the patient can, of course, be encouraged to revenge himself by some vindictive feelings directed towards the German leaders, and that is good so far as it goes.

He has never met these people in real life—they are lay figures modelled on what he gets from newspapers. The results of such fanciful hatred are often most disappointing…

A great commentary that still rings true in today’s political climate.
