Self-denial (also called self-abnegation and self-sacrifice) refers to altruistic abstinence – the willingness to forgo personal pleasures or undergo personal trials in the pursuit of the increased good of another. Various religions and cultures take differing views of self-denial, some considering it a positive trait and others considering it a negative one. According to some Christians, self-denial is considered a superhuman virtue only obtainable through Jesus. Some critics of self-denial suggest that self-denial can lead to self-hatred and claim that the self-denial practiced in Judaism has created self-hating Jews.
