Harry doesn't have enough hatred (even for U-No-Poo) to produce a powerful enough curse
when wizards duel, they use what ever spells come to mind quickest and all his life he's been using Expelliarmus and Stupefy etc. so in a quick-thinking duel, Avada Kedavra doesn't come to mind
even Harry isn't a poweful enough wizard
it goes against his beliefs
is that enoguh for you
no
No. Harry Potter was hit by the killing curse in Harry Potter and the Deathly Hallows however, it only kills the part of Lord Voldemort's soul that was in Harry.
Avada Kedavra, also known as the Killing Curse
He used Expelliarmus, and Voldemort used the killing curse, Avada Kedavra and, he wasn't lucky, the curse rebounded on him, so Harry won.
He faces him in the forbidden forest but granger kills him with the killing curse.
He did not die. He married and had three children. A small piece of Lord Voldemort's soul was in Harry Potter, making him a Horcrux, and when Voldemort hit Harry with the killing curse, supposedly killing him, he killed the Horcrux inside Harry.
Harry survived the second curse, known as the Killing Curse (Avada Kedavra), during the climax of "Harry Potter and the Deathly Hallows" due to the protection given to him by his mother, Lily Potter. She sacrificed her life to save him, creating a powerful magical shield that transferred to Harry. When Voldemort cast the curse on him, it rebounded because of this ancient protection, ultimately leading to Voldemort's own temporary defeat. This bond of love and sacrifice was the key to Harry's survival.
Avada Kedavra, the killing curse.
No but maybe in Deathly Hallows.
The killing curse.
After Neville Longbottom cuts off Nagini's head, Voldemort loses his last Horocrux and returns to his mortal stage. (There are 7 horocruxes.) Voldemort dies by the Elder wand (which belonged to Dumbledore.) backfiring on him by the famous killing curse,"Avada Kedavera."
The Killing Curse- Avada Kedavra. He kills them in their house at Godric's Hollow
