What is the primary role of a jury in a criminal trial?

The primary role of a jury in a criminal trial is to determine the innocence or guilt of the accused. This function is fundamental to the jury system, which is designed to provide a fair trial by involving a group of peers who assess the evidence presented during the trial. The jury listens to the testimonies of witnesses, examines the evidence, and ultimately decides whether the prosecution has proven the defendant's guilt beyond a reasonable doubt. This standard of proof is a cornerstone of criminal law, aimed at protecting individuals from wrongful convictions and safeguarding the principles of justice.

In contrast, facilitating plea deals typically falls within the purview of the prosecution and defense attorneys rather than the jury. The sentencing phase is generally handled by a judge, who considers various factors, including the severity of the offense and any previous convictions, after a verdict has been reached. Furthermore, serving as legal counsel is the role of attorneys, not the jury, which is meant to remain impartial and focused solely on the determination of guilt or innocence based on the evidence presented.
