i just want to point out that i love the concept of an INFJ villain. They have certain qualities that make them somewhat relatable, but you can't agree with their methods. They always have the greater good in mind, even though they are willing to make sacrifices, which brings the difficult moral questions. To me, that makes the best kind of villain, the kind that can route all the people for a cause, a bigger picture, not just a plain evil person that wants absolute chaos, but a relatable human being that got lost on the way. INFJ villains: ra's al ghul, Loki, Yagami Light, Uchiha Itachi(although technically not a villain), and of course Zaheer.
