This is interesting because I theorize that the wand functions to 
focus magic power just as a laser focuses light energy.  Obviously, 
young wizards must learn to focus and channel their power, that's why 
they attend Hogwarts.  Emotion is a factor, too.  We know that a 
happy, positive emotion is required to conjure a patronus.  And on the 
other end of the emotional spectrum, Bellatrix taunts Harry in the 
atrium of the MOM:
 
"Never used an Unforgivable Curse before, have you, boy?" she yelled.  
She had abandoned her baby voice now.  "You need to mean them, Potter! 
You need to really want to cause pain--to enjoy it--righteous anger 
won't hurt me for long--I'll show you how it's done, shall I?" (OOP p. 
810 USed)

So what was going on on top of the tower when?:

Snape gazed for a moment at Dumbledore, and there was revulsion and 
hatred etched in the harsh lines of his face.
"Severus . . .please . . ."
Snape raised his wand and pointed it directly at Dumblecore.
"Avada Kedavra!" (HBP p. 595-6 USed)
