Yet , to be able to use the curses on one, would require an immense and all consuming desire to inflict the pain,or the desire to kill or the desire to possess, one to do evil.
The killing curse, the most evil of all the curses, that tears a soul apart of the one who casts it, leaves no sign... , it is so believed.
But yet, there is one boy , who stands an exception... Harry Potter....
If one could recollect, during the fight at the ministry in the 5th year, Harry, attempts to use the unforgivable curse against Bellatrix Lestrange, it isnt as effective as it is to be and Bellatrix tells him , "you've to really mean it boy..."...
Well, what is the point I am trying to get at ... well it is , Voldermort tried to kill harry , using the Killing curse , but it didnt really fall through and worse still it backfired....and the man who cast it, was reduced to a merely ghostly existence.
Could it be , that Voldermort didnt really mean to? Or was distracted , by a stray thought about , if he was right in identifying Harry as the one, if his deduction abt the person was indeed right and although it is never told to us, but it is the first time, Voldermort was possibly killing a baby and not an adult and if that had indeed distracted him... to not believe the prophecy...and it is that which caused... the curse he cast , to fail ... and backfire?
I do not in anyway intend to associate humane qualities to Voldermort, but the possiblity of the arrogance of being invincible inducing a fleeting moment of self doubt abt his inference of the boy who shall vanquish him...
I for one feel , that , although it has been told to us.... by the author , that no one was able to figure out why the killing curse and the power Harry had was that of love... , the reason for the killing curse to fail... seemed to be revealed to us .... in a strange and subtle way.... in the books and for me , the fight at the ministry and Harry trying to use the unforgivable "Cruciatus" curse on Bellatrix, I felt it was a giveaway, the unforgivable curses too , could fail... and worse backfire...
And yeah Harry was able to save himself agaisnt the killing curse yet again... during his fourth year, but by this time, we all know, Harry had been imparted with power by the Dark Lord himself , which would mark him as his equal!
