What is the worst sin? I would say arrogance is the most evil sin. I define arrogance as:
A way of thinking that one’s view is correct, relevant or irrelevant of any information that is present. This thinking results in anger, and leads to hate, something that is occurring in the world today.
What is this way of thinking, and how does one get arrogant? This way of thinking manifest itself by emulating and listening only to authoritative figure like your parents, religious figures, professors or anyone one considers important (sometimes even oneself). It is a way of thinking that requires no reasoning, but only requires one to obey to a doctrine or a person. This is why fact and evidence does not matter to these arrogant people. They are on the right side because religion or someone who is important to them tells them they are right. Fact or evidence goes right out the window; they are on the right side. The right side becomes the truth for them. This false truth easily brings upon the emotion of anger when they are challenged on their views. Anger is an emotion that lessens our reasoning functions; these functions are already compromised in these arrogant individuals. Look at the Black Lives Matter movement in this country, and the Islamic Terrorists. Anger then brings upon hate and violence, which are prevalent in these two factions.
Anger can only be fueled by arrogance; and like a fire that is fueled by dead trees; anger can be easily spread like wild fire. When arrogance is lessened, anger will not spread; and violence will cease to exist. This is why I believe that arrogance is the most evil sin that is plaguing the world today.
