You could argue that Harpuia wasn't one to question the mentality of trying to run everything yourself. He certainly didn't see any reason to shoot that ideal of X's down; perhaps the sacrifice that he would inevitably make in the future wouldn't prevent the energy crisis, Elpizo's hubris, or the return of Weil, but it had been for the sake of the world.

He mulled this answer over in silence for a moment, expression giving away nothing. Truth be told... he wasn't even able to claim with any certainty that X would even have the chance to change Harpuia's past. The discrepancy in their memories may have suggested time travel, but Harpuia was reluctant to accept anything so utterly irrational.

"You're just as I imagined you'd be," he told X, and simply left it at that, lapsing again into silence as he focused on continuing their search.
