But if your character was of good alignment then he may see the Revenant as an evil character, and kill him, not knowing what he may do with the dagger.

However you could always look at it the other way, your character would possibly give the dagger back so the revenant could finally die in peace. And Hentold asked you to deliver it, so you are just doing as he asked.

If you were evil you may just kill him outright, wanting the dagger for yourself. Or you may not even kill him, but just leave him, so that Hentold still gets the nightmares (if that would work, it may be passed on to you, but you would soon see.)

If you were neutral I suppose that is the hardest one (and I am neutral.) You may have no reason to kill the revenant as he has done nothing wrong to you, and also Hentold has asked you to deliver the dagger back, so you may just do as the man asks. You are also letting the revenant die in peace, which could be seen as a good thing. Or, you may decide to kill him as he could possibly be a threat to others with the dagger, afterall, you do not know what he will do when he gets it. Also you may think that the dagger might be a nice item for you, which could help you protect yourself.

Just a few justifications.
