Why did deku lose this fight?

bakugou fought because he wanted deku to show why he was chosen, he wanted deku to prove himself and fail, and when he defeated deku it didn't change anything, it was a fight he couldn't win. Bakugou wanted Izuku to show why he was chosen by the All Might. If Deku had beaten Bakugou, narratively it would have proved his point "I'm stronger than you, therefore I'm better than you" only instead of Bakugou being the strongest, it was Deku who was. Winning that fight meant that Bakugou had to live with the fact that, no matter how strong he became, Deku was the one chosen by the All Might, Deku was more heroic than him, for Bakugou the hero is the one who always wins. He is simply one of the most honest characters in the series, yes he doesn't have a sad story, he is just petty, and no, he didn't take a beating to change, he simply had to live in an environment where his behavior didn't inspire fear or admiration, everyone knows how strong he is, but they just think he's silly, his excesses of anger only generate shame in others and no one takes him seriously. And it was SO ORGANIC, I wouldn't trade it for anything.
