"Premeditation" means that the intent to kill must have been formed prior to the act itself. It is not necessary that the purpose to kill preexist in the mind of the accused for any definite period of time. The mental state of the accused at the time the accused allegedly decided to kill must be carefully considered in order to determine whether the accused was sufficiently free from excitement and passion as to be capable of premeditation.Amended by 2022 Tenn.
