[Fullmetal Alchemist] how was it "fair" for al to lose his entire body?

when ed and al tried to do human transmutation to resurrect their mother, ed lost his leg but al lost his WHOLE ASS BODY. usually, when human transmutation is attempted, truth only takes a single body part. such as when izumi lost her internal organs when trying to revive her child.

but for some reason, truth decided to take al's ENTIRE body, even though he already took ed's leg. if ed wasn't there to "revive" al by binding his soul to the armor, al would've just been...dead. 

so i ask...how is that a fair trade considering the other sacrifices made during human transmutation?

Brotherhood covers that, the Truth doesn't care about fairness, it's about equal trade, Al wanted to feel the warmth of his mother's embrace, so it took away his entire body, so he wouldn't feel any warmth ever again.

It's a punishment for trying to cross a line that the Truth established.
