There are so many evil ENFJs in the fiction that you don't need to put the label on everyone! It spoils the fun.
I'd probably go with INTJ, because of his amazing determination, planning, vision etc. He's an Introvert all the way - take for instance the whole monologue about how he hates people, or check his house in the final scene: a behemoth that is made to guard him from any encounter with people.
Even his speech he used to convince people was copied every time and said with no true emotions.
