"The standard of review for improper closing arguments that provoke timely objection from opposing counsel is whether the trial court abused its discretion by failing to sustain the objection. In order to assess whether a trial court has abused its discretion when deciding a particular matter, this Court must determine if the ruling could not have been the result of a reasoned decision. State v. Jones, 355 N.C. 117, 131, 558 S.E.2d 97, 106 (2002) (citations and quotation marks omitted).
"The standard of review for assessing alleged improper closing arguments that fail to provoke timely objection from opposing counsel is whether the remarks were so grossly improper that the trial court committed reversible error by failing to intervene ex mero motu. In other words, the reviewing court must determine whether the argument in question strayed far enough from the parameters of propriety that the trial court, in order to protect the rights of the parties and the sanctity of the proceedings, should have intervened on its own accord and: (1) precluded other similar remarks from the offending attorney; and/or (2) instructed the jury to disregard the improper comments already made. State v. Jones, 355 N.C. 117, 133, 558 S.E.2d 97, 107 (2002) (citation omitted).
