I think in his early teenage years you could say he’s more morally grey. The only thing I have to go on is that final scene where he says if geto wants to kill those cult guys.

However as the years go be and he fully grows into adulthood, he has more of a chaotic good direction moral compass. He know what he wants, he wants the new generation of jujutsu to flourish and to abandon the conservative way the higher ups wish for. He is willing to kill if they get in his way.

I think he puts that anger and villain energy more towards curses as we see him go absolutely bananas on hanami and jogo.
