I destroy negatives that I don't want, though not immediately. I keep the negatives and contacts around long enough to learn what I did wrong. Sometimes it can take me months to learn why a certain image doesn't work; sometimes I realize that the image does work. For me, throwing bad negatives away is cathartic. It means that I believe that I can do better and there's no reason to waste time or storage on dead wood. It's always better to look forward at new possibilities than backwards.
Cheers, James
