Most people are so ungrateful to be alive

What I revere about is that the two creators thought of the cheapest script by just chaining two men to their opposite sides of a prehistoric bathroom with a dead body in the middle of the floor and he is the reason they are locked in the room.
Interesting turns were when it is revealed that Zepp was another victim following rules to obtain antidote for a slow-acting poison he was given.
And as Zep's tape ends, corpse rises and is revealed to be Joe Kramer, the real Jigsaw Killer.
Jigsaw chooses his victim under these principles:
Most people are so ungrateful to be alive.
Sick of people who don't appreciate their blessings.
Sick of those who scoff at the suffering of others.
I read about the fact of how Leigh Whannell came up with the idea for the character Jigsaw, juggled between his tumour and MRI scan. Sitting nervously in the waiting room he thought, "What if you were given the news that you had a tumour and you are going to die soon? How would you react to that? And thus he imagined Jigsaw giving his victims in the literal version of the situation, but only giving them a few minutes to choose their fate.

Notable lines:
To overcome something, you have to admire what a perfect engine it is.
That's how you fight disease.
