Sergeant-Major Morris is the man who brings the monkey's paw to the White's home. On the surface, it seems that he is afraid of the paw and it seems that he wants to destroy it. After all, he throws it in the fire, which would seem to indicate strongly that he wants to be rid of it. We also know that he fears it because of what it has done to others (and, apparently, to him).
But he must be somewhat ambivalent about it. If he hated it and feared it that much, why hadn't he gotten rid of it long before. And why didn't he act much more strongly to keep the Whites from having and using it?
So it seems to me that he does fear the paw, but on some level he wants someone else to have it so they can have the bad "luck" he had.
