I am usually a very courteous, polite person. Taking an act of revenge against a person you think has done you wrong is a bit of a different scenario.
Perhaps you mean that we should channel that anger into something constructive, such as donating the time used to plot demise for something worthwhile. A charity, a church function (if that's your thing), or a shelter could benefit from the energy you exude that your anger created. Put it to good use!
