well, given that our choices and actions are determined by some factors and circumstances, hence replacing the idea of free-will with causality, people are and still held responsable for their actions, I mean, crimes are determined by psychological factors as well as personality, learned behaviour, learned experience and genetic/biological traits.
Psychology, psychiatry and neurology seem to confirm this, take sociopaths, psychopaths, schizophrenia, as examples of this, and they are held responsable and punished for their actions, well, except for perhaps schizophrenia?, and even things such as personal disputes or anger problems, you could argue they had the free-will not to do it, but I would say it wouldn't be exactly the case, from my observation, I would say that most likely, people act the way they act because of the way they are and how they have been brought up, and determined by few circumstances, psychology being one.
For the sake of convenience, necessity and control, likely, the concept of free-will have been stated in society, but that's just an idea regarding the issue of free-will and determinism.
Mental incompetence or mental illness is a legal defense against being held entirely accountable for one's actions. Also, highly paid attorneys frequently get their clients off the hook, guilt or innocence being irrelevant.
But in general, we are held accountable for our actions. As you said, for purposes of convenience, necessity and control-- the concept of freewill is used as a justification for meting out punishment and keeping society in order. On the other hand, if the majority of people did not believe in freewill, then what? What would happen if people started writing to their political representatives demanding that no one be singled out for punishment any more; that either we are all guilty and deserve punishment or no one is guilty and therefore none deserve punishment.
