Yes, Because on the paragraph 420 where it explans that
" Waiting to see his swift hard claws
Grendel SNATCHED at the first geat
He came to, RIPPED HIM APART , CUT
HIS BODY TO BITS with powerful jaws,
DRANK THE BLOOD FROM HIS VEINS and bolted."
Means Grendel doesnt want people who makes a place noisy , So Grendel want ti eat those people .
