Short on time tonight, I'll just quote this perspective on the subject;
... Frankfurt cases ...
... Strawson ...
Frankfurt cases are simply thought experiments regarding special circumstances where the person is theoretically unable to do otherwise but might still be assessed as acting of their own free will. For example, suppose a neuroscientist implants a device in Bob's that will only allow Bob to vote for a Democrat. However the device is only activated if Bob is about to vote Republican. So, if Bob is already inclined to vote for the Democrat, the device is never activated. Bob, is still acting of his own free will even though Bob could not do otherwise.
The correct analysis of this problem is that any manipulation of Bob constitutes an undue influence, and is therefore not free will. But if the manipulation never occurs, then Bob is acting of his own free will.
P. F. Strawson was looking at the problem of responsibility from the standpoint of the reactional attitudes that people naturally have toward harmful behavior. But that opens the door to justifying feelings of revenge and retribution. So, this adds nothing that is morally useful.
The Principle of Alternative Possibilities is satisfied in a more logical way, by looking at the logic of the language. A possibility is something that may happen, but then again, it may never happen. It is never necessary that a possibility must happen in order to be considered a real possibility.
The language and logic of possibilities evolved in our species to deal with matters of uncertainty. It is often the case that we do not know what will happen. So, we evolved the notion of possibilities to help us deal with this uncertainty. When we do not know what will happen, we imagine what can happen, to prepare for what does happen.
A possibility exists solely within the imagination. We cannot drive a car across the possibility of a bridge. We can only drive across an actual bridge. However, we cannot build an actual bridge without first imagining at least one possible bridge. In building a bridge, we are most likely to imagine many possible variations, and weigh the benefits of these alternative possibilities, before deciding upon the final design.
A real possibility is something that we are actually able to do if we choose to do it. It remains a real possibility even if we never choose to do it.
So, while we are limited to having a single inevitable actual bridge, we can have as many possible bridges as we can imagine.
The same applies to the choosing function. Choosing begins with a state of uncertainty. "What will we choose to do? Will we choose A or will we choose B?". We don't know yet. And we will not know until we've performed our evaluation of both options, to estimate which option is likely to produce the best outcome.
The logic of choosing requires that (1) there be at least two real possibilities (A and B) and that (2) we are able to choose either one ("I can choose A" is true and "I can choose B" is also true).
If there is only one possibility, then we bypass the choosing operation and proceed with the single possibility. It is logically impossible to choose between a single possibility, so, choosing simply would not happen. But, if there are two possibilities, and we do not know yet which one we will choose, then we must perform choosing before we can proceed.
In the same fashion, if we know for certain that "we cannot choose A" or that "we cannot choose B", then we would not bother choosing, but would simply proceed with the option that we could choose.
So, whenever we enter a choosing operation, it will always be the case that there are at least two options, and that we can choose either one.
Therefore, whenever a choosing operation occurs within a causal chain, the Principle of Alternative Possibilities will always be satisfied, by logical necessity.
At the end of the choosing operation, say between A and B, one of our options will become the single inevitable thing that we "will do", and the other option will be the inevitable thing that we "could have done".
By the logic and language of choosing, "I could have done otherwise" will ALWAYS BE TRUE, and it is only "I would have done otherwise" that will ALWAYS BE FALSE.
And this should put to bed the issue of the Principle of Alternative Possibilities. Sleep soundly.
Now, what about responsibility? We assign responsibility to the most meaningful and relevant cause of an event. The nature of the cause guides our efforts of correction. For example, if the cause of a criminal act was a significant mental illness, then correction will require medical and psychiatric treatment. If the cause of the bad behavior was coercion, then we remove the threat. If the cause of the act was a person's deliberate choice to profit at the victim's expense, then we need to take some action to correct the way the offender thinks about such choices in the future.
The nature of the penalty for a deliberate act would be designed to serve justice. We create a system of justice to protect everyone's rights, as defined by law. So, the penalty should be limited by that objective. A just penalty would seek to (a) repair the harm to the victim if possible, (b) correct the offender's future behavior is corrigible, (c) protect others from harm by securing the offender until his behavior is corrected, and (d) do no more harm to the offender and his rights than is reasonably required to accomplish (a), (b), and (c).
