Pride caused by Low Self-Esteem
Some people will use big words to demonstrate their academic superiority over others. These people have usually been called dumb or stupid. Some people like to use force to make their point. These are the people who have been bullied. Social media and the internet has made it easy for people afraid of confrontations to say things to a complete stranger that they would never say to a person in real-life. The need to always be right is stupid.
Several teachers and religious leaders wanted to be the disciples of Jesus. Two tried to justify their righteousness before the Lord. They were unable to admit they might be wrong and were unable to follow him. The tax collector in the Temple claimed he was righteous before and he walked away without any justification before the Lord.
We are humans. We can't be right all the time. And thats why we need a Savior.
