Which amendment protects against cruel and unusual punishment?

The Eighth Amendment is the correct choice as it explicitly addresses the issues of cruel and unusual punishment. This amendment is a fundamental part of the United States Constitution that aims to protect individuals from excessive bail, excessive fines, and especially from harsh and inhumane treatment in the legal system.

The protection against cruel and unusual punishment is crucial in maintaining human rights and ensuring that individuals do not face barbaric or disproportionate penalties. Historical contexts, such as practices considered barbaric at the time of ratification, shape our understanding of what constitutes cruel and unusual punishment. Courts often refer to this amendment when evaluating the constitutionality of different forms of punishment and treatment in prisons.

The other amendments listed serve different purposes: the Fifth Amendment addresses rights related to legal proceedings, such as the right to due process; the Seventh Amendment pertains to the right to a jury trial in civil cases; and the Sixth Amendment guarantees the rights of criminal defendants, including the right to a fair trial. None of these amendments directly addresses the issue of cruel and unusual punishment, thus reinforcing the uniqueness and importance of the Eighth Amendment in protecting individual rights.
