you need to go study some chaotic dynamics about the consequences of actions in complex systems and how long the latency of consequences can be
just a simple example... the sun from time to time has explosions on its surface caused by plasma and electromagnetic effects
when one of those blasts happens, it takes 3-4 days before it gets in range of the orbit of earth
"metaphysics" is literally the entire category of things that are in the long to extremely long range of consequences of physical events
your short sighted view of cause and effect is completely ignorant of the fact that the more complex a system gets, the greater its latency, thus, this "can't break the rules" dictum only applies to the timescale of the event in question
gravity reacts in nanoseconds
what makes you so sure that morality doesn't react in a span of your life?
