I completely agree with the concepts other people have put forward.
I think one of the most terrifying things about 'the machine' is that it felt pain and anguish in the knowledge that it would have to kill. The saviour machine has been made so human it is imperfect, just as the humans who built it are. A secondary message to this could be that perfection is unachievable for imperfect beings such as ourselves.
