Nah he repeatedly puts kids in danger as a means to motivate adult subjects. In Saw, Jigsaw forced Zep to tie up Gordon’s wife and child and threatened to kill them if Gordon failed his test. In Saw II, which is what I think you’re referencing, it’s true Jigsaw intended for Eric’s son, who was placed into the game, to survive, but not putting him in any danger is a stretch considering the door trap at the beginning which he could just as easily have fell for and the fact that he could have been killed by Xavier. Saw III has the clearest case proving this wrong where it’s revealed at the end of the movie that Jeff’s daughter was kidnapped by Jigsaw and hidden in a room running out of air, with Jeff having to win another “game” to save her.
