>>56738244Giovanni, at worst, put his business/capability as a trainer above his son. Still bad, but not the first time.
Ghestis manipulated N since birth and promptly disowned him as soon as N lost, calling him "a freak without a human heart."
If you decide to factor in Pokemon Masters, Giovanni is implied to still hold respect for his son despite Silver making it clear that he hates him for his weakness. For bonus points, this was during Ghetsis' event, where he tried to manipulate N and had no regrets even after N helped save him.
