The most Slytherin-like way of killing? think it's Avada Kedavra or sessions of Cruciatus or anything? PS i'm not a sadist :)

Definitely Avada Kedavra, you cant kill with crucio...you can just make then insane, like the Longbottoms.

Avada Kedarva and the other unforgiveable curses, they like to cause people heartache and intice fear into other people that they see beneath their blood status.

Avada Kedavra of course, it's quick. And green.

Make someone kill itself with Imperio

Imperio a random stranger with no links to yourself or the victim to do the killing. Makes the crime virtually untraceable.

avada kedavra you can't kill with cruciatus

I think it would be Avada Kedavra. It's very qucik, easy, and not messy. Crucio and Imperio are kinda like full-blown Death Eater methods of killing or torture ending up in a killing.

I think a true Slytherin would make it quick, easy, simple, and so that no one would know that it was them and they would never get caught.

cruciotis curse then avada kedavra!

I Think Imperio Then Make The Victim Use Avada Kedavra On Themselves
