Harry did not spare Sirius Black!

I've read a number of posts throughout this message board with the 
argument that Harry spared Sirius' life in the Shrieking Shack 
because he did not kill him.  Have you ever considered that Harry 
hesitated with Sirius because he didn't know how to kill him?  Harry 
had never heard of the AK curse (at least as far as we know) until 
the 4th year when Crouch!Moody showed it to the class.  Crouch!Moody 
himself said that he thought the whole class could AK him and he 
wouldn't get so much as a nose bleed because it is extremely advanced 
magic.  Now, we know Harry is magical and all, but he couldn't even 
get a summoning charm to work properly in the 4th year without loads 
of practice!  At most, I think Harry could give Sirius a fernuculus 
or jelly legs curse.  He couldn't do anything seriously damaging in 
the Shrieking Shack.

Now, I don't say this to actually argue that Harry had evil 
intentions in the Shrieking Shack even though he did not have the 
means to effect his evil intentions.  I make this point only to 
suggest that we cannot point to the Shrieking Shack and Serius as 
evidence of Harry's benevolence.  Certainly we can point to Harry's 
decision with regard to Pettigrew for this purpose, but not Serius.

Thoughts?
