I'm going to get so much hate for this, but Hagoromo aka SO6P is a bad father. He bred two sons, Indra and Ashura. He gave Ashura the most attention and neglected Indra despite that Indra was the best of the best. Hagoromo shut Indra down from the title of being ruler even though it was his birth right (Complete insult) and started an endless war between both sons. His negelect and backstabbing ways caused endless bloodshed to their descendants, the Uchiha and the Senju as well.
