Answer: I'd like to think that if I had somehow managed to survive an apocalyptic zombie uprising and then accidentally chainsaw'd into another human being I think that I'd die just from the shock.
Answer: Glen doesn't saw Monica's arm off. He just saws into her body which is what kills her and then Glen dies as a result of the bus crash and from accidentally murdering an innocent woman.
Chosen answer: Glen was alive when he accidentally sawed into Monica. He was killed as a result of the crash.
