The spirit within
The other part of personality is based on character, which is a result of the choices we make as we go through life. Ted Bundy was an extreme example of an ENTP lacking in moral qualities. He devised a method of using charm and the appearance of being injured and needing help to lure women to locations where he could kill them. He also studied law enforcement methodologies and used that knowledge to evade capture by using disguises, killing without using a gun, minimizing physical evidence at crime scenes, and committing crimes in many different locations across the United States.
We are all spiritual entities, having physical experiences while our bodies are alive. Think of it this way:
Physical bodies are like hardware.
Temperament is like firmware, permanent software that has read-only memory. It can be used, but cannot be changed.
Character is like software we develop ourselves, and can be modified if desired.
