Dumbledore's glint

Reading the books again a thought occured to me
 
  I think that the reason for Dumbledore's glint may be related to 
the nature of the killing curse. We have been told that if the 
killing curse hits you your dead no matter what, so I'm assuming 
that if you get hit in the foot your dead. Taking this one step 
further if the killing curse hit one blood cell (u see what im 
getting at now) you would be dead. 

  From this you would assume that Harry could not cast the killing 
curse on Voldie without killing him self. If this was to work in 
reverse it would create an interesting  promblem for Dumbledore 
namely if he should tell Voldie. If Voldie was informed it would make 
killing Harry more difficult but if Voldie was not told he could 
accidentally kill him self. This could explain Dumbledore saying that 
he "loves Harry too much" at the end of OotF. 

  If Dumbledore was to take this one step further he could murder 
Harry ending all the problems in the wizarding world. 
 
  I know that's not going to happen but it would create an 
interesting problem
 
 
What do you think?
