Not really. When one thinks about ethics, one should take into account the existence of teleological ethics or consequentialism where "right" and "wrong" depends on the outcomes of the action.

As far as a person isn't aware of the outcomes of the action, he or she can't really judge if the action was "right" or "wrong".

Also due to the butterfly effects,in most cases a person is theoretically unable to produce objective judgement, thus leaving the judgement of the action in the "undefined" state.
