Dumbledore's Death and Why did Snape Comply

Personally, I think DD asked Snape to kill him.  I don't think DD was
pleading for his life or for Snape to "save his soul".  If Snape was
saving anyone from having blood on his hands, it would be Draco.

Now, the reason why DD wanted death.  There was a quote I was looking
for but can't find it.  It's said something about "the greatest
adventures are to be had after death".  So, it is possible that DD
thought he'd be even more helpful to Harry after death.  I thought
about that after McGonagall took Harry into the Headmaster's office
and there was a portrait of DD sleeping.  Also, what better way to
gain Voldemort's trust.  I think Snape was lying to Narcissa when he
said he knew Voldemort's plan for Draco.  I think he was trying to
gain information out of her.  So, being that he had an unbreakable vow
to Narcissa and DD was getting weaker (between breaking the curse on
the ring and drinking that potion), he asked for death.

Also, remember that two accomplished legilimens facing each other. 
Who's to say they weren't finalizing the deal before Snape hit him
with the unforgivable.

And just to sneak something else in this post.  If Snape truly wasn't
working for DD, why didn't he just kill Harry when he had the chance.
 He was busy shouting DADA lessons to him:

[pg. 603 U.S. Hardback edition]
"Blocked again and again and again until you learn to keep your mouth
shut and your mind closed, Potter!"

That tells me that he was giving Harry a chance.  Also, he stopped the other DE's from doing anything to him.
