[SPOILER] Plot Discussion Thread *Spoiler Alert*

I think it might also just be the Machine convincing Mandus that pain is sometimes necessary in order to save something and proceed, and not necessarily referring to Mandus himself doing one or any of those things? Or maybe referring to the pain and suffering in the coming wars, and how it will be better to just ''save'' mankind than have them cut off their flesh and feet in desperation.

The Machine talks about something Mandus did in the past.

The story isn't consistent. You make it sound like he cut his foot or had a gangrene but it never said anywhere nor implied.

No, the Machine makes it sound like he had gangrene and amputated his foot. The Machine asks Mandus about something in the past which Mandus clearly experienced. On the basis of Ockham's Razor, there's no need to invent a bunch of other stuff to explain how this doesn't mean what it says, and create a string of contradictions in the process.
