I don’t think David started a rebellion because he had a falling out with his sister or father (or even the king, I guess), but because of his arrogance that he believed he could do something very great to be proud of and maybe hoping to get recognition (and praise) from the people. Well, at least that’s the plan at first. But maybe because his stupidity (tied with arrogancy) he’s led astray by some of his (supposedly) followers, and so it became a rebellion

He could do that even with his eyes only… lol
