You could have done otherwise in a parallel universe where random stray particle of radiation interacted with a microtuble in your brain.

Why would anyone care?

Do you think alternate me cares as much about me as I care about him?

While I agree you could have definitely expanded a bit on this particular thread.. *hint*

It is reminiscent of another thread along the lines of free will vs. determinism. Myself I find pondering things that already happened have virtually no utility, same with taking the time to ponder and "feel" either liberated or restricted by the thought of either. What is, is. And what will be, will be.

I will say. Overthinking determinists are in fact predetermined to do less or at least have less motivation then one determined to believe in free will. I'd say this is a fact. True regardless of respective possibility.
