KrayZ33: Probably missed this completely, but when did Lust ever date 3-4 guys at the same time? I only remember her going out with Havoc to get information and that's it. Also find it a bit over the top to call her a slut, she hasn't acted like a slut from what I've seen at least. Also if I hadn't known she was Lust before hand I can't say that I would have known right away so not sure what you're basing it on.
So you don't think Sloth is appropriate based on how he looks. Well I don't know if I would say a little boy fits the description of Pride either or an middle aged man that doesn't really look angry most of the time as Wrath.
Prof. Chaos: I don't know some personalities doesn't fit their names, while for some the abilities feel appropriate for their name Gluttony is the prime example of personality and ability fitting the name, Sloths ability don't fit while his name is more accurate while Envys ability is appropriate in my opinion, though his personality isn't so much envy imo or if you rather Lust's personality doesn't her name.
Anyway don't remember exactly but didn't Hoeinheim mention that the homunculus represent things that Father had thrown away and reshaped them into the homunculus. Thinking about how Pride said the emotion wraith doesn't exist in him. So shouldn't that mean that they don't represent each deadly sin to a tee or our general idea of them but rather represent that part of Father.
