Not really, under South Carolina self defense law and SCOTUS case law on use of force by the state, objective reasonableness is still required. While subjective belief is one half of the legal test used for self-defense in South Carolina (as it is in all U.S. jurisdictions in most cases), objective reasonableness is most often the only thing in question since it is extremely difficult for the state to prove beyond a reasonable doubt that the defendant did not have a subjective belief.
