David did not allow Abishai to destroy Saul because he wanted to avoid being guilty before the LORD. In 1 Samuel 26:9-11, we see that David had the opportunity to kill Saul, who was pursuing him to take his life, but he refused to do so, saying that he would not lay a hand on the LORD's anointed. David believed in the judgment of God and did not want to take matters into his own hands by killing Saul. He also recognized that Saul was still the king of Israel and wanted to respect his authority.
