Not the pretentious faggot with good insight into the story-anon but it seems like the mangaka needed Mustang to perform human transmutation but didn't think through it well, and did a horrible asspull. Non of it makes sense
>Mustangs punishment:
Up till this point it only took physical things, limbs, organs and entire bodies, Al's souls was just moved onto the thing they transmutated, but for Mustang he took his eyesight, which is pretty vague, might as well just take his eyes.
>The truth punishing Mustang
There's no reason for it, he was somehow, "forced to be part of a human trasmuttation, he didn't even do it, how come he get's punished, I get there's a price for opening the door, but it would seem there's no moral just a toll to pay for opening the door, which doesn't fit well to the ironic punishments.
>Pride transmutating
This is never explained/foreshadowed or touched upon, until this point all alchemy done by homunculous is either regeneration or something extremely specific
I'd agree this is one of the major plot holes and probably a sign of rushing.
