No. That would be a significant mental illness that removes the person's normal control of their behavior.
Unchecked OCD is more aptly "a will that is free", but not an example of "a person acting with free will", unless the person with OCD accepts and does not question their behavior.
It may even be a case of... Well, let's assume you have multiple variants of the will to decide for oneself. Each variant describes a "way" you are free, a will which generates a report describing that you did this yourself...
Well, it's entirely apt for a system inside any given human to report that a will is "freely held" on the dimension of "came from within the skull" but not freely held on the dimension of "no matter how I resist, I still compulsively do this thing".
This is why I discuss the "special will", the "will to choose for oneself" in general terms, as the freedom of particular wills to generate an identification of "freedom" in some respect. Its why I don't define the specifics of it.
Of course some people are oblivious even to the nature of their own behavior. They may do something slavishly, thinking they have available to them, if they were to choose otherwise, to do so even when they do not have this power.
This describes some drug abusers, and why we intervene with them despite the fact that "they can quit any time they want" despite the fact that they never do actually quit, even when they want to.
The compartment with the addiction's will to be free is stronger than the will of the agent who hates the fact that there is a part of them that needs a fix.
To that end, it can get rather hoary to discuss 'free will' because 'the will to decide for oneself' has various available roots of 'self' with varying applicability.
In fact learning to pay granular attention to the various ways that various wills to decide for oneself with respect to particular organizations of neurons express freedom, one can discern more readily whether the reason they wish to do something is OCD or something they wish to do.
It can allow the person to more readily sculpt which sources of wills are allowed freedom, and under what circumstances.
