Wow... that's just... Wow.
From a strictly game-related POV, I wonder how the 'PC's' are going to react to all this going on outside of their influence. I understand that it's not entirely right to compare OOtS to a actual game, but there are precedents, so I'll go ahead and do so.
If it were MY game, the player who proposed killing Miko at the outset would feel justified in their initial opinion and would henceforth murder any paladin the team encounters. Or anyone wearing blue.
But then, PC's who want to save the day shouldn't get killed. Or miss with arrows. Or spend all thier spells on mooks. The list goes on.
