If you say “an event is determined”, in order to be meaningful, you have to specify, explicitly or by context, that the event is determined by whom.
Similarly, if you say something is free, you have to specify “free from what” or “free with respect to what”.
free ~ independent of
Without a grammatical object, the phrase “independent of” is meaningless, unless the context has implied what that grammatical object is.
free [without an object] ~ free from everything
is meaningless, because the word “everything” is meaningful only if it has a context.
