I see what you are saying, but it upholds my point doesn't it? If it is unpredictable then there can be no strict causality.
the relationship between cause and effect. The principle that all events have sufficient causes.

If you take this to the extreme, everything that happens today is just an effect of an initial cause. Thus causality.
I do not believe that. I believe that I make choices that are influenced, but not caused by others.
