nah, I think moving Butcher into the chaotic good realm is a smart play. He is inherently good in the show, even if massively self important.
He has a moral compass, him saving Hughey is a perfect example of this. I dont think him having reservations about a supe kid changes anything or leads him down the path of turning into a "bad guy".
Him and MM are both motivated by different things, but both are also characters you root for as they are seeking justice in the name of defeating Vought/evil.
There are enough bad guys/pricks/assholes in this show already, they dont need to move Butcher into that category. If anything I think it would hurt the show.
