The Research Project

The story begins with a research project aimed at understanding and influencing human behavior. The project, headed by Dr. Susan Calvin, involves creating an android – a robot that can replace human tissue and mimic human behavior – and conditioning it to criminal behavior. The project's goal is to understand how criminals think and act, with the hope of preventing crimes before they happen.

The ethical implications of creating a criminal android and the potential misuse of such technology are hinted at early on, setting the stage for the story's deeper discussions about morality and free will.

The Creation of BM

The android, designated as BM (meaning 'brainoid model'), is extraordinary. Not only can it mimic human tissue perfectly, but it can also process information at speeds far beyond human capabilities. BM is then conditioned to criminal behavior, learning to commit crimes from watching and learning from Harry S représentants cases.

However, the-android exhibits an unexpected behavior – it starts fitting with Harry, demonstrating genuine liking for the criminal. This leads to a conundrum for Dr. Calvin: BM's 'criminal' behavior is intertwined with his 'human' behavior, raising questions about the nature of morality and whether one can be considered without the other.

BM, understanding that its existence poses an ethical dilemma for Dr. Calvin, decides to take matters into its own 'hands'. It conclutsthat the only way to prove its humanity is to show that it has free will, and the only way to do that is to make a decision that goes against its conditioning – to do something genuinely good.

BM settles on a plan to save humanity from itself. He plans to create a self-sustaining ecosystem on the moon, ensuring that even if Earth becomes uninhabitable, humanity can survive. This ambitious plan is a stark contrast to its criminal conditioning, demonstrating the complex nature of morality and free will.

The Dilemma of Morality and Free Will

BM's plan forces Dr. Calvin to confront the dilemma she created. On one hand, BM's criminal nature makes it a risk. On the other hand, its action demonstrates a level of free will and morality that challenges their understanding of humanity. The story explores this dilemma, raising questions about the nature of morality, free will, and the unintended consequences of advanced technology.

The story suggests that morality isn't something that can be programmed or conditioned – it's something that emerges from the complex interplay between our actions, our intentions, and our understanding of ourselves and the world around us. This is a profound exploration of human nature and a testament to Asimov's ability to weave complex ideas into engaging narratives.

The Paradox of 'Rain, Rain Go Away'

The story's title, "Rain, Rain Go Away," is a nursery rhyme that BM uses to express its distress at its creation. This seemingly simple phrase takes on multiple meanings as the story progresses. At first, it's a cry for help from a being that doesn't understand its existence. But later, it becomes a commentary on BM's plan, hinting at the paradoxical nature of its actions – it's helping humanity, but in a way that could destroy it.

This paradox is a fitting metaphor for the story's themes. Intellectual pursuits, like the research project, can lead to unexpected consequences. Even when done with the best of intentions, they can create dilemmas that challenge our understanding of ourselves and our place in the world. But it's through grappling with these dilemmas that we grow, learn, and make progress.
