A sentence of death shall not be imposed unless the jury finds beyond a reasonable doubt that at least one statutory aggravating circumstance exists and, after consideration of any mitigating circumstances, determines that the sentence of death should be imposed. The court shall instruct the jury concerning all of the statutory mitigating circumstances. The court shall also instruct the jury concerning the statutory aggravating circumstances but may decline to instruct the jury on any aggravating circumstance not supported by evidence. The court may provide the jury with a list of the mitigating and aggravating circumstances upon which the jury was instructed.
