crucio and sectumsmpra

then avada kedavra

then imperio

Avada Kedavra is instant death, no suffering, and crucio and sectumsempra make you suffer. Imperio controls you, so same as above

Imperio, I hate being controlled by anyone...

Crucio causes no lasting damage, Avada kedavra is quick and painless, and Imperio isn’t necessarily used for a dark purpose. sectumsempra causes the most damage without treatment.

Avada Kedavra

Crucio and Sectumsempra are kinda similar, but Crucio doesn't leave physical scars on you, it does mentally. I still think Crucio is worse

sectumsempra kills you though…

Not always

I think Crucio is the worst. After all, death lasts but a moment. Being tortured and being haunted by those memories would do so much damage.

If anyone knows about "Vulnera Sanentur", the healing spell for sectumsempra, then crucio is the worst
