If one understand how the butterfly effect works, it is clear that it cannot be used to achieve any particular outcome: events that are "on the knife's edge" depend on basically all small perturbations that ever happened in the past, in a pseudo-cryptographic way. You can't tell that small perturbation X will result into Y without nearly perfect knowledge of the entire system, because any other unknown small perturbation anywhere might flip the result.
