I know we didn't hear much about him in OoP, but I'm sure Karkaroff's 
a dead duck. He seems to me to be the one LV referred to as "too 
cowardly to return" (because he knows he's toast if LV or a DE gets 
within wand range). He can't be the one who's "left forever," b/c 
Karkaroff struck me as still being on the dark side, just too chicken 
to take his chance at redemption by throwing himself at LV's feet and 
asking for mercy. Snape's got to be the one who's "left forever," 
because whatever else snape might be, he's not too cowardly for 
anything (wonder if the Sorting Hat ever considered him for 
Gryffindor). I've been surprised to see posts that seemed to imply 
that Severus is still LV's boy, and I think, not a chance. Not the 
most vanishingly small chance. I'd love feedback on Karkaroff or 
direction to good threads discussing him.
