Humans should have the right to die with dignity

Some people promote the idea that humans should have the right to die with dignity (see https://www.deathwithdignity.org/ ). Several states have legalized physician-assisted suicide (PAS). However, others may argue that a doctor prescribing a deadly prescription violates that doctor's Hippocratic Oath or claim that suicide by any means is immoral. Doing research and taking into consideration the actual laws concerning when and how a confirmed terminal patient would be able to request PAS, make an argument that it is or is not a moral action. Also see if you can find Kant's famous argument on the immorality of suicide. Does he have a point or are there just some times when the morally right thing to do is to allow a person to end his or her suffering?
