Deathknights are evil, surely, in that sort of I once was a goody-to-shoes and now I'm gonna wear black sort of way. So they can raise the dead, we got demons and last I checked a demon could still chew the head off a dead body. They wear plate because they're afraid they might get hit, we wear cloth because we know nobody can touch us. A deathknight simply sounds like a dead knight... while a Warlock sounds like a battle.

Yeah, they got a touch of evil, and I wouldn't mind incorporating them into my evil schemes. But they'll fill the roll of the dumb muscle I manipulate to further my own plans.
