Infinity Castle fights discussion (manga spoilers)

So...

Douma didn't take the fight seriously,

Akaza basically gave up because his memories took over,

Kokushibo came to realisation that his dreams of becoming the strongest and not admiting defeat turned him into a literal monster, basically giving up. He realized he went TOO far.

Like, it felt like they all gave up. If it wasn't for their memories holding them back, I don't think the Hashiras would have won.

What are your guys' thoughts?
