I honestly think what Noel did here was a kindness (an unintentional kindness, but still). The other party was basically stuck in hell. They were all (besides the captain) miserable in their situation and unable to keep up. Sooner or later the party would’ve collapsed or they’d have been completely wiped out if this fight had happened in an actual combat situation.
noel let the party collapse in a much more peaceful manner and hopefully they can all go out and find new parties or new lives that better suit them.
