In the Harry Potter universe, the killing curse Avada Kedavra along with two others (the torture curse Cruciatus and the compelling curse Imperious) are known as the unforgivable curses. Their usage results in the utterer if found guilty sentenced to life in the wizardly goal Azkaban. This is completely understandable given that words in the Harry Potter universe have very real physical effects.
It’s not quite the same in our sticks and stones world though is it? Or is it?
By lying, you could conceivably convince people to perform actions they would not otherwise have. Through taunts and insults, you would probably induce a certain amount of emotional pain in your victim. Through constant harassment, you could possibly push the truly vulnerable into suicide.
Perhaps, given that we are all spell-casters, silence is truly golden. Alternatively, we could maintain such a relentless positivity that only blessings fall from our lips. But in either case, would you be using your powers responsibly? After all, to hold back is itself an action: “First they came for the communists and I didn’t speak out because I was not a communist.”
Spell-caster, are there circumstances where you would risk using the unforgivable curses?
