Do causes not have effects? Does not every action have an equal, but opposite reaction?
Does energy not take the path of least resistance? I can see no true reason why free will in the non-deterministic sense exists. It would be nice if it did, but on an objective level, I don't see free will in the philosophical sense to be an actual objective fact.

However, does this change anything regarding thoughts, words, and actions? From my experience, no, because no matter if effects can defy their causes or not, I still do as I do and you do as you do.
