zgirnius:
The problem with the increasing corporeality argument is that 
Voldemort was fully corporeal at the time he cast the curse, and 
remained so for a good twenty years. I think I'll go for the 'curses 
that stay too long get worse' argument instead.

Another thought I had was that maybe Voldemort's personal involvement 
with the curse magnifies it. The only two to die were Quirrell and 
Crouch, Jr. One possessed by Voldemort while under the curse, and the 
other a Death Eater. Of course, this would suggest ths curse should 
also take a particularly malign form for Snape, ss he too is a Death 
Eater. (I mean, in the sense that he still has that mark...so a 
magical connection to Voldemort, whether or not he still wants it). 
And the other three holders we saw really were more problematic, I 
would hope, than the average teacher who has held the post. (Lockhart 
and Umbridge because they are bad people, Lupin, because he does have 
a bigger and more dangerous secret.)

zgirnius:
I think Dumbledore wanted Snape to still be at Hogwarts when 
Voldemort returned. And with the DADA curse, there was a possibility 
that would not work out if he gave Snape that position. Dumbledore 
always intended to send Snape back to spying on Voldemort (as he did 
when Voldemort returned in GoF). And, to help get Snape initially 
accepted back to the fold, Snape had to have something to offer 
Voldemort-. And that, Dumbledore always planned to be his position at 
Hogwarts in close proximity to Dumbledore. Something he knew 
Voldemort valued, as he had ordered Snape to seek employment there 
himself.
