Why can a judge reduce a sentence?

A judge can reduce a sentence for several reasons, including mitigating circumstances that may have influenced the defendant's actions, the defendant's cooperation with law enforcement, or evidence of rehabilitation. Additionally, a judge may consider the principles of proportionality and fairness, taking into account the severity of the crime and the defendant's background. In some cases, statutory guidelines or plea agreements may also provide grounds for a sentence reduction. Ultimately, the judge has discretion to ensure that justice is served appropriately.
