What is the meaning of the word rehabilitation in the law realm?

Context:

Free will is the ability of http://en.wikipedia.org/wiki/Agency_(philosophy) to make http://en.wikipedia.org/wiki/Choice unconstrained by certain factors. Factors of historical concern have included metaphysical constraints (such as logical, nomological, or theological http://en.wikipedia.org/wiki/Determinism), physical constraints (such as chains or imprisonment), social constraints (such as threat of punishment or censure, or structural constraints), and mental constraints (such as compulsions or phobias, neurological disorders, or genetic predispositions). The principle of free will has http://en.wikipedia.org/wiki/Religion, http://en.wikipedia.org/wiki/Law, http://en.wikipedia.org/wiki/Ethics, and http://en.wikipedia.org/wiki/Science implications.^[1] For example, in the religious realm, free will implies that individual http://en.wikipedia.org/wiki/Will_(philosophy) and http://en.wikipedia.org/wiki/Choice can coexist with an http://en.wikipedia.org/wiki/Omnipotent http://en.wikipedia.org/wiki/Divinity. In the law, it affects considerations of http://en.wikipedia.org/wiki/Penology and http://en.wikipedia.org/wiki/Rehabilitation_(penology). In ethics, it may hold implications for whether individuals can be held http://en.wikipedia.org/wiki/Moral_responsibility for their actions. In science, http://en.wikipedia.org/wiki/Neuroscience_of_free_will may suggest different ways of predicting human behavior.
