[quote=@Ellri]oh, and another, more theoretical question: Say a person has no favorite character, how can they kill their favorite character?[/quote]

Even if you don't have a pre-ordained 'favorite' per-se, it's inevitable that you are going to like one character and dislike another more than the others, all relative to each other of course. Take a moment to sit back and think about which one you like the most.

If you come up with a complete tie, see the Clarifications section on having more than one favorite character, since the situations are equivalent.
