They are just staying true to the concept that dominant alphas are psycho, if they are normal then they will do the normal.
I'm actually quite shock many people thought like he should do the normal way when the story already keep saying they are not normal.
Am I the only one thinking he might just ignore it and close it again? I'm quite sure when he heard the boy about his situation he thought it was normal. Though maybe, to show he was helping he goes inside with the kid instead.

Mc is genuinely ludicrous because wdym he found a kid locked up in his basement, and his first thought wasn’t “oh the doors unlocked, and there’s a bunch of fire fighters around, let’s get him out of here” INSTEAD IT WAS “let me jump in and willingly imprison myself alongside this kid so he’s not lonely
