Corrected entry: Jigsaw says he's never killed anyone in his life, but in the first Saw, when Detectives Sing and Tapp find Jigsaw's lair, Sing chases him and hits a trip wire, causing several shotguns to go off, killing him. Sing didn't know about the trap, therefore had no choice. So Jigsaw killed him.

Correction: Jigsaw, for all intents and purposes, is a psychopath who's simply found a way to 'justify' his actions. Notice how he slashed Tapp's throat in a manner that should have been fatal. In Sing's case, his thought process was probably, "it's his own fault he got killed - he should have been situationally aware."
