If I'd kept his behavior toward my shinki in mind, it'd be more practical to let him die.

[Were Hibari to die, he'd experience some hard reset, but he can't imagine there aren't side-effects like there were in Monad. Not the sort of thing he suspects that he can discuss with a shinki, not when Add also came from that place...

Still, watching that and doing nothing didn't sit well with him]

But I'm not very keen on pointless suffering. It wouldn't have been a swift death.
