Snape didn't make the Unbreakable Vow

I really like this idea!  I'm curious, though, what your opinion is 
regarding why Snape killed Dumbledore, if there was no Unbreakable 
Vow.  Do you think he did it simply to carry the double agent 
deception on?  I think, Unbreakable Vow or not, that that's probably 
the case.  The first time I read the scene on top of the Astronomy 
tower, I thought right away:  "Dumbledore doesn't plead.  The only 
thing that could scare him to the point of pleading is the thought of 
the Order losing their inside man.  He's pleading for Snape to carry 
out their plan, not for Snape to spare him."  (Reminiscent of Obi Wan 
willingly choosing to die.)  Then I began to wonder about whether 
Snape had said "Avada Kevadra" out loud but silently cast a different 
spell, allowing Dumbledore to come back (a la Gandalf) in the 7th 
book.  JKR has shot that down, of course.

Anyway, I think your theory, if true, would add an extra sprig of 
tragedy to the bowl, since Snape could have chosen not to kill.  I'm 
not, however, necessarily saying that Snape shouldn't have killed.  
This very well could be an Obi Wan "If you strike me down I shall 
become more powerful than you can possibly imagine" kind of 
situation.  I'm reserving judgement on that until Book 7.
