>>13342765>Say I'm destined to be a murdererWhat is this "destiny"? It can't be based on your knowledge since it's something you can't know. It can't be based on something physical, because the distant future isn't physically determined by the present (because of true randomness at small scales and chaotic systems at large scales, and possibly due to limitations on what can be known/measured)
You could simply suppose that you were going to commit a specific murder at a specific time in the far future, but, again, that's not actually determined in the present, so destiny seems an inappropriate way to describe it.
Then let's consider a situation in which you might conceivably commit a specific murder in the immediate future, and restrict our attention to those cases in which the decision to commit the murder appears to be free in the everyday sense. (In the cases in which the decision doesn't appear to be free, we both can agree that it isn't.) Now, if the decision is free in the everyday sense, your choice is unrestrained in some sense (you are free of restrictions or coercion, for example being threatened or physically forced to move) and your decision is determined by your intentions, emotions or desires (you choose to commit the murder because, to some degree, you wanted to).
