Different choice suggests that that there's an expected outcome, and that there can be an unexpected outcome,
It suggests, but it it doesn't have to be that way. A different choice might carry no expectation with it - though that would not be the normal human behaviour. Humans tend to automatically predict potential outcomes, but favour some over others, depending on those opinionated feelings.
Are we just running toward a certain future, a result of the cascading events of the past. The path we follow, determined by the pavement before us, installed by past hands unseen?
So, are we fated? I have thought a bit about this and technically, I think that we are fated, where everything happens in some kind of ricochet that is far too complicated for us to ever know or predict with accuracy. Yeah, there are some quantum mechanics things that are meant to be random, but are they truly random, or do we just not know their formula yet?
