YA'LL. The only reason why the Pacifist ending even happened was because of Flowey. He doesn't have a soul, he can take whatever soul he wants, so he took the six human souls and all of the monster souls, those monster souls made a whole of one single human soul and with that he had seven. The reason the monsters can't just use eachothers soul is explained in the game itself; they can only absorb HUMAN SOULS and they can't absorb MONSTER SOULS while humans cannot wield any, so they'd be forced to take six human souls. Only a being with no soul such as Flowey can take the souls out of someone and put it back afterwards, he has no restrictions, that's the only reason he can become a god. And the monsters can't simply group up and break the barrier, because they can't use the souls if they're not dead, they can only manifest it through magic, and they can't even kill and get everyone's soul because they can't absorb MONSTER SOULS anyway. The only way is either through Flowey or getting all of the SEVEN HUMAN SOULS. Have a good, beautiful, wonderfull... day.
