@SOL_rocks Don't worry, either the children will magically disappear and be exempted from being killed or they will somehow turn out to be absolute evil in the most comical ways.
I'm not excluding a "Scott Tenorman Must Die" plot either.
@Doomer There's also the fact that they lost any capacity for reason, they could just have destroyed the wooden doors to drink water and probably the blood of villagers in the process.
