When Cedric was pulled from the Goblet of Fire, he was already toast. In order to be sorted, all students must be alive. Must be a rule. Anyway, I realized that when Cedric was down in the lake, it didn't occur to him to save everyone. He was only interested in winning. Harry on the other hand felt responsible for all the water hostages. So Cedric wasn't cut from the same cloth as Harry although I thinnk time would have made him a more compassionate person.
