Why banishment is useful for dealing with people who have committed crimes?

Banishment can serve as a useful tool for dealing with individuals who have committed crimes by removing them from the community, thereby protecting public safety and reducing the risk of further offenses. It also allows for a form of rehabilitation, as the individual may have the opportunity to reflect on their actions in a different environment. Additionally, it can alleviate tension within the community by addressing grievances associated with the offender's presence. However, it is essential to consider the potential for social isolation and the effectiveness of reintegration upon return.
