Oh, that's different. That is totally a sensible reason not to trust 
someone, or to think they are 'OFH'. But the word double agent may be 
used to describe anyone who ends up in that specific both-sides-think-
he-is-working-for-them type of situation regardless of how they got 
there. It is possible to use that term to describe any flavor of 
Snape, including DDM!.

zgirnius:
I think your post was quite clear. I don't think the argument applies 
to DDM!Snape, but it makes sense. DDM!Snape changed sides, of course, 
not for threats or for money, but out of remorse for having made the 
wrong choice in the past. Which to me seems very different. The sides 
are not equal, and Snape's stated reason for picking one over the 
other reflects something intrinsic to the side he chose. If 
Dumbledore is right about Snape's reasons, he has nothing to worry 
about until he starts to go around killing babies and their parents 
on the off chance they might grow up to threaten his power.
