Obviously, he "knew what he  must do" by then as well. So no, 
the obvious theory probably won't  carry.<<

No? But Voldemort took Pettigrew back, and Peter was 
suspected  of having betrayed his master too.  Peter also spent  
years under the protection of the Weasley family,  noted 
supporters of the Ministry and champions of Muggles and 
Muggleborns. 

How *was* Peter able to convince his master that he hadn't 
betrayed him, anyway?  Perhaps Voldemort believed him 
because Voldemort thinks he always *knows* when people are 
lying to him. If Snape has a way to defeat that power, and it's 
hard to see how he could have ever been a successful spy if he 
hasn't, then Voldemort will think he can believe whatever Snape 
tells him.


I can't agree with your interpretation of Snape's speech to 
Karkaroff. To whom was Snape going to make Karkaroff's 
excuses, if not Voldemort?  If, that is, we can believe what Snape 
says at all. There's a very strong hint from the Sphinx that spies 
don't tell the truth.
