Self-righteousness

Self-righteousness (also called sanctimoniousness, sententiousness, goody-goody attitudes, and holier-than-thou attitudes) is an attitude and belief of moral superiority derived from a person deeming their own beliefs, actions, or affiliations to be of greater virtue than those of others. Self-righteous individuals are often intolerant of the opinions and behaviors of others that they deem to be less virtuous.
