Potioncat:
I've sometimes wondered if DD expects Snape to betray him, thus "I 
trust Snape."  that is to betray me.  And he is keeping his close to 
watch him.  (I hope not.)

vmonte:

Potioncat:
I come from it differently.  Saying up front, this is my 
interpretation.  I think DD is well aware of Snape's faults but sees 
his virtues/strengths as well.  DD knows Snape has a miserable 
personality, but knows he has a vast knowledge that he can teach to 
the students and knows that he will lay down his life to protect 
them.  I think Snape went to the Shrieking Shack to protect the 
students not for revenge.  (Of course, he might  have enjoyed 
revenge.)

So I believe DD tolerates Snape's behavior.  I'm not sure if that is 
what JKR is saying, but for the moment that is what I think.
