The monologue at the beginning is Kaz, because he talks about his missing arm AND leg. Snake's only missing an arm

And you hear Snake answer Kaz at the end when Kaz says "Take back everything they took from us" and Snake says "Kaz, I'm already a demon."

I think "Big Boss' fall into villainhood" doesn't necessarily mean he will be a villain, it's just how the world perceives him.
