So it seems to me that there are two different flavors of Fe. The first type of Fe is the typical Fe that you first think of: It deals with caretaking, hating to see others hurt, feeling others emotions, liking harmony between groups, knowing what others needs are, giving, etc. This type of Fe is the good Fe so I have entitled it "Jedi Fe". When I imagine Jedi Fe, I think of individuals like "Mother Teresa" and "Martin Luther King".
Now that's all find and dandy but there seems to be a secondary sort of Fe that never quite makes it to the definition books. The second kind of Fe is what I consider "Sith Fe": Evil Sith Fe deals with being obsessed with social prestige, putting others down in front of a group in order to build up their own self esteem (example: "What you're still wearing that! That's so out of style.), using your ability to know what others are feeling to manipulate their emotions to get what they want, and being obsessed with fitting in. A perfect example would be like your typical bitch Prom Queen in any given high school, teen movie and Patrick Bateman from "American Psycho".
