Self-Righteousness
Clinging to their beliefs and opinions as absolute truths, self-righteous individuals refuse to consider alternative perspectives or admit their fallibility, creating conflict and division by dismissing those who don't share their views as misguided or immoral. Self-righteousness is ironic in that it often arises from a desire to appear virtuous and good, despite true virtue and goodness being attainable only through openness, empathy, and a willingness to learn and grow rather than rigid adherence to one's beliefs.
