Every Time Harry Potter Used Unforgivable Curses (& Why Not Avada Kedavra)

The Unforgivable Curses are three of the most deadly spells within the Harry Potter universe, and while he’s no dark wizard himself, Harry Potter uses these forbidden spells more than once. The darkest of the Dark Arts, the Harry Potter unforgivable curses are the Cruciatus Curse, the Imperius Curse, and the Killing Curse. Although the curses are illegal, Harry uses Unforgivable Curses, but only once he is thrust into the Second Wizarding War. While many of Lord Voldemort’s Death Eaters continued to use them illegally, Aurors had permission to cast the spells during both Wizarding Wars — and while never given permission, Hogwarts student Harry Potter uses some Unforgivable Curses too.
