Hector knows hes being played and yet he still falls for it. The only reason he is alive is because they need him to make monsters. He knows it. They know it. Everyone knows it. They say it out loud. But poor stupid Hector falls for the honeypot anyways.
No good would come from engaging with his captor. We are not told or shown what Hectors true motivations might be so we have to take everything at face value. And that is telling us that Hector's really naieve and he thought Lenore was ready to betray her family for him. They could have handled this better for sure.
