The reward for doing right is mostly an internal phenomenon: self-respect, dignity, integrity, and self-esteem.
Laura SchlessingerIntegrity, honesty, and honor may not give immediate rewards or gratification, and they can be life-threatening (for example, being a whistle-blower or turning state's evidence). The absence of integrity, honesty, and honor do not always bring punishment or scorn, and can be life-aggrandizing (connivers and cheats often gain power and wealth). Therefore, morality must be its own reward.
