assisted suicide vs. euthanaisia

So a possible topic for my research paper could be assisted suicide and it's effects, causes, what poeple think of it. Apparently it is different from euthanaisa and that could be a possible angle i could work from. Assisted Suicide is not legal in the USA, but is legal in a select few places in Europe. Assisted suicide is when someone else helps take the life of another with the permission on the other. This is usually done by a doctor when the patient is in times of suffering. Although I think that suicide is never the option, when someone is so close to death and suffering either mentally or physically from the present circumstances, I think that it becomes a logical option to consider. There was a case in the United states where the wife was in a coma and she was not getting out of it, and the husband wanted to pull the plug while the family wanted to keep her living on a machine. The husband ultimately requested that she be pulled off the machine, and she died. The family set a law suit against him for killing her. But i htink the man was right in the sense that he had full rights by marriage and having the one you love living off a machine is no way to live a life. His choice was hard, but understood. The family claimed this was assisted suicide/ homocide. But that is wrong because she didn't speicify that she wanted to die. ANyways That is a good topic to choose. :)
