^^^ This statement is in contradiction to the one below:
Of course a decision can be altered, but it will, in my view and even that of many compatibilists who say we have free will, still be the only decision possible for that person at that time. There seems to be no way around this. In other words, if you were literally in that other person's shoes, you would have done what they did. No way around it, apparently.
You simultaneously hold that 1) a decision can be altered and 2) only one path is possible. You simultaneously hold that 1) the chosen decision is the only possible decision that could have occurred and no others are possible and 2) disagree that appeals to likelihood, possible consequences, and prevention are reasonable and relevant under that framework.
ETA: In case you're missing this... if there is only one possible decision, then the likelihood of any other option is zero. If there is only one possible path, then the opportunity to prevent an outcome is always either 1 or 0, and is assigned after the fact, not as a prior possibility. If in retrospect the outcome was avoided, then the likelihood of prevention is 100%, if the outcome was not avoided, then the likelihood of prevention is 0%.
What I meant was, to clarify,
choices can happen, including for example changes to plans (simple example, I decided to go for a run but then I watched tv instead)
but both the changes and the final decision (and action) are inevitable (barring random curve balls). I have never yet read of any explanation as to how it could possibly be otherwise, no matter how unpalatable or paradoxical some might think it to be, or how much of a brainache it gives us to consider or what the implications are.
Worse perhaps, it is all, it would seem, bound (literally) to be happening ('to us') automatically, even if stochastically, despite us thinking 'we' are steering it. They (our thoughts, decisions and actions) are probably, in the absence of a better explanation, being steered by what we might call the laws of physics and they, and our lives, are part of the natural unfolding of the universe.
I still think that when Einstein said that if the moon were by some possible means to become self-conscious, it might think it was continuously guiding itself around the earth, it was a nice analogy, albeit simplistic.
