Lex Luther

His personality type is that of an unhealthy ENTP. His ego is brittle, especially when he is intimidated or thinks someone may make him appear foolish. He is a contentious & judgemental person. As a form of protection, he tries to justify his behavior not to mention he's very secretive & tends keep people out of his life because he is insecure. He also seldom stays with one thought for very long. While charismatic & conscious of social limits, healthy ENTPs are not always concerned with their influence on others; the latter are more likely to be indifferent to these factors. They come off as callous & indifferent. In this instance for Lex, this is undoubtedly the case. As he is perceived as being conceited & hard to get along with.
