F - Molly - consequences be damned, she's hot and a nice girl.
M - Mab - She's kinda my type
And I may be reading too much into this, but I think that Mab is a genuinely nice person who does bad things because she has to fulfill a role.
K - Hm... this is a difficult one. I can't say, that there are any characters that I dislike enough to see them permadead. Oh wait! Rudolph! Yep. Rudolph the brownnose is one to get killed ASAP.
