If this world were viewed as a human body, then humanity would be its cells and bacteria. When their numbers multiplied to the limit the world could bear, the world would fall ill. And if they deteriorated into cancer cells, the world would be on the brink of destruction.
Of course, the world would not willingly perish. It had its own immune system, and that immune system was called Apocalypse. War and famine would arrive first, followed closely by plague, and finally, the ultimate arrival: death.
After all that, the population would plummet, the world's cycle would regain balance, and everything would return to normal.
But anyone who had ever been sick knew that relying solely on one's own immune system to fight disease and recover was a long and painful process. One careless mistake could mean failing to resist and dying outright. Even if one survived, severe aftereffects might remain—hatred.
So when faced with a serious illness, the best approach was to take medicine quickly. And the role Gabriel wanted to play was that of a cure.
There would be no need to fear entering a terrifying, desolate war, nor would anyone need to face agonizing famine, because none of that would happen. Before the immune system activated, she would eliminate all the excess bacteria. And she would use advanced targeted therapy, killing only harmful bacteria and cancer cells.
However, the aftereffect called hatred seemed unavoidable. But you would not need to hate one another. You would only need to hate me. I will bear all the hatred in this world alone. I will bear all the evil of this world alone!
"If you shoulder all the hatred yourself, then the survivors, having someone they all hate—a common enemy—will become relatively united." Mephisto now understood all of Gabriel's thoughts.
