"Guilt" is remorse for having committed some offense or wrong, real or imagined. It is related to, although distinguishable from, "shame", in that the former involves an awareness of causing injury to another, while the latter arises from the consciousness of something dishonorable, improper, or ridiculous, done by oneself. One might feel guilty for having hurt someone, and also ashamed of oneself for having done so. Philip Yancey compares guilt to the sensation of physical pain as an indication that something should not be ignored but attended to. Rabbi David Wolpe says, "Facing up to the hurt we cause others with cruel speech or callous acts, and to our myriad failures to meet the marks God sets for living a true and good life, "makes forgiveness meaningful, not merely a catchphrase".
