Snapedom

Sorry, I must agree to disagree here. The only real Dark Magic spells in the books do nothing else but hurt the victims of those spells. Sectumsemprs means forever cut. Snape wrote the spells for 'enemies'. Enemies tend to be alive. If their dead what's the use of cutting them up and there are planty of spells for cooking. We see Molly casting a spell on her cooking knives to cut up potatoes. I rather doubt she was using Setumsempra. Besides Snape himself classified it as Dark Magic. His words to Harry were that he didn't know that Harry knew such Dark Magic when Harry was stupid enough to use the spell on Draco. There has to be some that qualifies spells as Dark, the Dark spells we see hurt people. I do think it is that simple.
