It is of course OK to feel anger, but don't let it lead you to hate, as that is a downward spiral. The most famous quote saying much the same thing comes from the original Star Wars movie:
"Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering."
But our quest to overcome anger will lead to the other spiral, towards positive emotions and thoughts. To the area where we can lift others up, without having to descend to the lows they find themselves in.
