During the related quest, he will have the following conversation with Lieutenant Aldononde:
Private Glalor: They're almost like the spinners from back home. Couldn't we spare them, sir?
Lieutenant Aldononde: What part of "no survivors" don't you understand, private? These savages are the enemy. Once they complete the ritual, they die like the rest.
Private Glalor: But, sir!
Lieutenant Aldononde: If you're so keen to argue, talk to the Alchemist, It's his order.
Private Glalor: Sir, I ... yes, Sir.
