.. it's true, isn't it. As kind of depressing of a thought as that could be, Inigo knows they're right.

"Don't you ever get tired?"

Even as he's saying it, Inigo is - ironically enough - still trying to cut down soldiers, just to get them to stop for a moment.

"Of-- Of all this. Of fighting."

Maybe the middle of battle isn't the best place to ask that. But in Inigo's opinion, it is. It gives Soldat less time to think about why Inigo is asking that in the first place, after all, and avoiding thoughts or questions about that is his entire intention.
