There is an important difference between Atman and Soul. Thoughts, emotions, decisions are seen as part of nature/prakriti not Atman, whereas Soul is usually intended to include these things.

A better description would be that the atman is the consciousness in which physical things or mental constructs can appear and pass away. The nature of pure consciousness is also described as real(undisturbed by time) or ananda/contentment/bliss.

The disidentifcation from thoughts (for instance, seeing them pass by just like cars on road) is an important part of liberation.
