Explain the two different meanings for Jack’s words when he says to Ralph, “Couldn’t let you do it on your own”

Jack is going for help, and someone declines it.

his tongue, i believe, was bloody and hanging out of his mouth.

he looked as if he were hungry.

he has several wolf-like qualities; a gray coat, sharp claws and yellow fangs.

those eyes made me feel, dear reader, like the end was near.

as i reached for a stick, he moved to the other side of the hill.

panting and hungry, he looked at me, a defenseless human and he snarled.

well i said my prayers, however, he simply turned and limped off. 

d would be your anwser i belive, hope this .
