The last of the classically trained tumblrinas

I fail to see how the Monsters of Inc. were persuaded to care about the welfare of children who to them were no more than an anonymous, alien resource necessary for the convenience of their lives. They weren't even the same species of them. Yet they overhauled their whole energy economy to be more humane toward this hated other, which had no legal rights in their society, and which most of them had never even seen. It really makes no sense, if anything it's sort of a perversion, like if you actually lived with that level of concern and empathy you wouldn't be able to function at all. You would be, just, fucking debilitated. Just psychologically crushed. Idk it's just not that plausible to me. And Randall, the lizard. He isn't that fuckable either.
