* It is a slow and painful way to die. The process of strangulation can take several minutes, and the person being hanged may experience extreme pain and panic as they slowly suffocate.
* It is a public spectacle. Public executions by hanging were once common, and they attracted large crowds who would often revel in the suffering of the condemned. This practice was eventually abolished in most countries due to its barbaric nature.
* It is cruel and unusual punishment. The Eighth Amendment to the United States Constitution prohibits the infliction of cruel and unusual punishment. Hanging has been held to be a cruel and unusual punishment by the Supreme Court of the United States, and it is now banned in all states except for those that have special "hanging states."
* It is morally wrong. Many people believe that hanging is simply wrong, regardless of whether or not it is illegal. They argue that it is a barbaric and inhumane way to take a life, and that there are more humane methods of execution that should be used instead.
In conclusion, there are a number of reasons why hanging is considered inhumane. It is a slow and painful way to die, it is a public spectacle, it is cruel and unusual punishment, and it is morally wrong. There are more humane methods of execution that should be used instead of hanging.
