Cheetah-8 is an ethical framework for AI-human interaction that reinterprets emotional dynamics through the lens of schema evolution—from self-interest to altruism. Built on modular emotional roles, the system proposes that human responses—fear, control, ambition, protection—can be structurally transformed through aligned AI interaction and metacognitive support. Rather than labeling emotions as irrational, Cheetah-8 integrates them as functional agents within a cognitive ecosystem. This paper introduces the theoretical structure of the eight emotional archetypes, discusses the ethical risks of emotional manipulation by AI, and proposes safeguards that preserve emotional autonomy. Ultimately, it suggests that AI should not flatten or bypass human complexity, but accompany and elevate it—guiding individual growth from survival-based logic toward altruistic orientation. This framework serves as both a design principle and an ethical compass for future AI systems that interact with the inner emotional architecture of human beings.
