Jen: Well, that's what I meant, JKR already gave us a motivation for 
Dumbledore not wanting Snape to have the DADA position. I'm confused 
why you would buy this explanation, but not this one:

Jen: Being put near the dark arts and being put into a cursed 
position which brings 'out the worst in you' are two very different 
things in my book. Snape teaching DADA without the curse would 
likely be fine (extrapolating from what JKR said above). Snape 
infiltrating the DE's and being near the practice of dark arts is 
fine. Snape put in a position near the dark arts while under a heavy-
duty Voldemort curse is NOT fine, it would 'bring out the worst in 
him'. 

I don't see how this weakens Dumbledore's trust in Snape for him to 
worry that Snape won't be able to handle the curse very well--who 
could? No one so far. I've always felt Dumbledore is more protective 
of Snape than other people except Harry, and maybe in part because 
he knows how much he needs him to defeat Voldemort when he returns. 
So I could definitely see him being wary of putting Snape into a 
situation which could ruin everything because of a powerful curse in 
play.
