Why does Hamilton argue that tenure for good behavior is necessary for judges

Hamilton argues that tenure for good behavior is necessary for judges because it helps ensure the independence and impartiality of the judiciary. Without tenure, judges may be susceptible to outside pressure or influence, such as from politicians or special interest groups, which could compromise their ability to fairly interpret and apply the law. By providing judges with tenure, they are able to make decisions based on the law and the Constitution, rather than on the whims of those in power. This ultimately helps to protect the rights of individuals and uphold the rule of law.
