"The last temptation is the greatest treason: to do the right deed for the wrong reason"

This quote by T. S. Eliot talks to the idea that it is possible to do the ideal thing for the incorrect reasons. It recommends that even if one is doing something that is considered to be excellent, if the inspiration behind it is not pure, then it is ultimately a betrayal of one's own values. This quote is a tip that it is necessary to be conscious of our objectives and to make sure that our actions are driven by a real desire to do what is right. It is a warning versus permitting ourselves to be tempted by external benefits or recognition, as this can lead us to do the best thing for the wrong reasons. Eventually, this quote motivates us to be truthful with ourselves and to ensure that our actions are encouraged by a real desire to do what is right.
