i feel like he’s the last person to be hating on…bro got sa, and i feel like the reason he’s using them is justifiable, in a world where your grade level matters so much where he gets viewed as insignificant if he’s a D grade, but is admired when he reaches S grade, i think it’s stems from society and his personality is a product of it
Also he can gain a sense of power by believing he's the one choosing to do this with them, even though they're the ones that want it and it's just the requirement for the level. If he didn't rank up from this, what could he have done? He would have been a D rank and they might have lost patience and forced them self on him even worse with him being so much weaker.

i hate everyone in this series omg but the mc???? ARE YOU THAT STUPID
