I agree - I wish they had shown more of *why* Soldier Boy is a piece of shit. Only thing we really get as an audience is that he fucked up Black Noir (and who cares if a piece of shit beats the fuck out of another piece of shit?) or that he says/acts the way I would think a guy who lived during the WW2 era would think and talk.
The racist line felt off, but also kinda appropriate I guess? But as an audience I see SB as discriminating against everyone, because he sees almost everyone the same (theyre all just lesser than him). So having MM call him that was kinda off.
Otherwise, was a great season imo
