The main viewpoints are split between the idea of free will and the idea of determinism. The concept of free will suggests that people have the power to make their own choices, independent of any external or internal factors, which places the responsibility for our actions squarely on our shoulders. On the other hand, determinism argues that all events, including our choices, are predetermined by prior causes, and therefore, what we perceive as a choice is simply the inevitable outcome of a chain of events. A third viewpoint, called compatibilism, tries to find a middle ground by suggesting that free will can coexist with determinism; it argues that we are free if we act on our own desires, even if those desires are themselves determined. Ultimately, there is no single agreed-upon answer, and the debate continues to be a central topic in philosophy, neuroscience, and theology.
