She made her traps unwinable while Jigsaw, while the tools to escape were dull or the means of escaping made it extremely difficult, made his traps winnable because the goal was not to kill the people but to make them appreciate life and live theirs better
Don’t get me wrong, Jigsaw is shitty because he had no right to make these choices of who deserves this and needs to atone and who doesn’t because that’s God’s place not man’s but that’s a whole new thing
Amanda failed all of Jigsaw’s tests because she did not want to better herself or help people live better lives, she just wanted to get revenge on everyone for her suffering and allowed her rage to blind her to what was really her purpose at Jigsaw’s side
So yeah, she’s an interesting character and all but she makes me made because she refused to learn just what she was doing wrong EVEN AFTER HE RUBED HER NOSE IN IT AND SHOWED HER Laid it all out and she still didn’t see
