Being the villain isn't bad really, it's just that most of the INTJ characters are basically robots and talk monotoned. No one talks about the ones like Bruce Wayne from Batman, or Matt Murdock from Daredevil.
There is nothing wrong or lacking with the communication style of a female INTJ. It is normal for an INTJ. It's also normal for other types to "see" this in a completely different mindset.wrong but normal in their ability to understand.
I worked for 20 yrs for a certain Federal agency. It was said that people rose to the level of their incompetence - the more incompetent, the higher their position. Over the years, I observed this to be sadly true.
