You can say the same for Whitebeard, Garp, and any parent who ever wanted their kid to be something great, but their kid denied them.
The man's doing what he feels is right for his child. That's mad respect. Ain't no mf out here creating empires for their child. Ain't his fault his child a snake though. This mf about to put the whole world in War, just for his child to become the ruler of the most powerful empire.
