I saw websites pegging him as ENTJ.
Do you agree that he is ENTJ? The way he plot his escape from jail a few times, he does seem to use quite a bit of Te and Ni in here. He also has a deep interest in psychology and he always got very high grades in his psychology class.
But at the same time, I couldn't help but to wonder if he could be ENFJ instead. When his ex dumped him, he started holding a deep grudge against her, going out of his way to take revenge on her, he went all the way out to pursue her again a few years later but to end up dumping her like what she did to him, and then he starts targeting women who resembles his ex.
That revenge-plotting thing seems like an unhealthy Fe type to me, I can hardly see an Fi type plotting revenge against an ex.
