Monsters reverting back into mindless murderous creatures is good. Because it is nature and the natural order.
In this world that the Gods have created only violence, bloodshed and strongest and cruel survive and thrive. Therefore we must repent our sins, punish the wicked, kill the heretics and the unfaithful and all their families. Kill everyone, anyone and anything that does adhere to our faith and God.
Hail the Gods! The Gods will this!
