I would say obsessed, but if I'm wrong please forgive me as I don't really know the entire context of the story/text.
Explanation:
If it they are willing to take a whole hour for the narrator to put their head through an opening just to see the guy, then I would think that they are obsessed with the person.
He rips his arm off i remember. Grendel runs and eventually bleeds to death. So i will say beowulf murdered him. Also beowulf chops grendel's mother head off
