What is self righteous?

Self-righteousness refers to the belief that one's actions, opinions, or beliefs are morally superior to those of others. It often involves a strong sense of moral certitude, and the conviction that one's worldview or principles are the only correct ones. People who are self-righteous may be quick to judge or criticize others who don't adhere to their standards, and may be unwilling to consider alternative perspectives or ideas. Self-righteousness can lead to a lack of empathy, and may make it difficult to compromise or reach a consensus with others. It can also be seen as a form of arrogance, and may alienate others or harm relationships.
