Well...
That is indeed a dysfunctional group...can't really call it a team.
I must wonder, though, why the devil would your PC care about a luna moth? Unless he is an entamologist, that's the difference if the con-artist fighter exterminates it, other that the loss of a beautiful insect?
My son Alex really disliked a couple that were in my LA game group and asked me if I would be averse to his Avatar slaying one or both of the, I said in no uncertain terms that personal factors should not affect game persona relationships. He grumbled but agreed. However, when I was creating a Witchery Ability he immediately volunteered to test it out...suggesting a Warlock that hated the Avatars of the two other players he disliked. I declined to accept his offer. The two dropped out soon thereafter much to the relief of Alex, a the other players, and me
Cheerio,
