Demanding from a loved one to stay alive because you don't want to live through pain of loss, regardless of how much a person is suffering is what I consider selfish. In the end, we humans should be free to end our own lifes if we feel like doing it. I only hope that there will come a time when we can do it in a humane way. People should not have to jump in front of trains, from tall buildings, hang themselfs or cut their wrist when we have the technology to do it in a way that is less traumatizing and does not involve people that have nothing to do with it. I am in favor of professional suicide clinics/hospitals :)
