Everyone should have the right to die humanely. This archaic idea that only murders can be euthanized is ridiculous. I don't understand why murderers and violent rapists get to die more humanely than suicidal people.
I mean seriously, an evil man could go torture and murder 100 people and then get to simply go to sleep. I'm mean, literally go to sleep (lethal injection = "It kills the person by first putting the person to sleep and then stopping the breathing and heart in that order".) Think about how easy and peaceful that is. In addition, they get the luxury of leaving an unmutilated body for family members.
But a person whose only crime is having a mental or physical disorder, has to suffer severe trauma before dying. Either in fear (e.g., jumping, guns), pain (e.g., random drugs), or both (e.g., fire, drowning, etc.).
