It doesn't really matter what the hatred is directed at. The problem is that hate is uncomfortable, even when it feels powerful and empowering. It is only nice in comparison with worse emotions like guilt, shame, and fear. Hatred narrows the focus. It literally shuts down the senses and the range of emotions. It constricts the body. Peripheral vision is a great example of something that goes missing and the loss is unnoticed. Sounds become dull and flat. The mind is like an angry bee trapped in a small box, bouncing around against the walls - but it is not depressed or sleepy. It may be odd to see hate as an improvement over anything, but it can be. The problem is that it is still uncomfortable and painful compared to what can be experienced instead. At first moving beyond hatred can be worse than being in it - because of the tendency to gain ground only to lose it. It now hurts worse by comparison to something better. That's how it is with guilt and shame, after tasting how hatred was an improvement. Dropping back into a more painful emotion is more painful still after having had something better. That is the way the process works. People decide that they are done with something when it hurts too much to keep doing it.
