@KairoWasTaken from what I've understood doppelgangers are the physical representation of how people commonly see you (from what we've seen with Shinra). They are the idea behind your name in the collective mind. And his father was seen by everyone has proud, strong, caring for his people, and everyone knew he actually cared for his son. So even the Doppelganger would be proud of Beni's Nichirin.
