The Avada Kedavra – the killing curse from the Harry Potter Wizarding World is unforgivable, cannot be blocked, and is colored green.
The Killing Curse is a spell that causes instantaneous death and is one of the three Unforgivable Curses. Its incantation is Avada Kedavra. The only known counter-spell is sacrificial protection, which uses the magic of love. However, one may dodge the green bolt or block it with a physical barrier.
Protego and it's stronger counterpart, Protego Maxima, both wouldn't work to block the Killing Curse as it is mentioned in the book that Avada Kedavra is unblockable.
There is no way to block the curse - otherwise countless people could have easily been saved. The Abada Kedavra has no counter, cannot be blocked and is irreversible.
Avada Kedavra is the killing curse in the Harry Potter series. It is a fictional spell and cannot be blocked in reality.
In order to conjure the avada kedavra curse, you have to want to kill your victim. We all know that Voldemort could easily kill a child without an ounce of remorse... but not Snape. Snape didn't want to kill Dumbledore, and this was why the spell was blue instead of the usual green.
If you decide against learning Avada Kedavra from Sebastian, that's not the last chance you'll get to learn or use the spell. Once you return to the castle, you can visit Sebastian in the Undercroft in the Defence Against the Dark Arts tower, and ask to learn about it.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Though Harry encountered many opportunities that deemed Avada Kedavra necessary, it remains as one of the Unforgivable Curses Harry Potter never cast. For one, he viewed the spell as an immoral practice commonly used by users of the Dark Arts.
Some would say there's no spell worse than Avada Kedavra, the Killing Curse that Voldemort used so indiscriminately. But it's definitely not the wizarding world's only Unforgivable Curse.
8 Hermione Granger: Alohomora
If there is a spell to encapsulate the asset Hermione is to everyone's favorite magical trio, it has to be Alohomora. Alohomora is, fittingly, the spell that is used to unlock locks.

I've always suspected Molly's lethal spell was a particularly well-placed and powerful stunner that stops Bellatrix's heart, which is consistent with the description of her death: Molly's curse soared beneath Bellatrix's outstretched arm and hit her squarely in the chest, directly over her heart.
The darkest of the Dark Arts, Harry Potter unforgivable curses are the Cruciatus Curse, the Imperius Curse, and the Killing Curse. Although the curses are highly illegal, Harry using Unforgivable Curses happened, but he uses them once he was thrust into the Second Wizarding War.
