Sometimes, life can deteriorate to the point where a person loses their dignity and self-respect, and are unable to communicate; life like this is longer worth living, as the most enjoyable of things are no-longer enjoyable. Euthanasia could, in my opinion, be practiced when a person reaches this point, and then only passively. If the person in question is able to communicate rationally, then their opinion must be asked first.
Assisted death, other than passively should most definitely remain illegal, and in the Northern Territory, it should be made illegal. The nation of Australia must be uniformed, or else people simply go to another state, where the law different.
People should live their lives for as long as it is worth living, as defined above. Some people wish to use euthanasia to die when they are diagnosed with a terminal illness, and given a certain amount of time to live. These people still have those six months, or whatever. If they can, they should enjoy that time, doing all the things they like to do. If they wanted, they could go out and spend all their savings, or retirement money on things that “I always wanted to get one”, or make themselves feel good by donating to charities. They should not look at the amount of time they don’t have, but instead, at the time they have left. And besides, we all know we are going to die, these people are no different, except they know exactly how much time is left. It has been said that trials and pain make us stronger. Even if someone is in pain, that pain could make them mentally stronger than if they give up and take the easy way out. Life is full of pain, and joy, everyone goes through both things in their lives, because that is what life is.
Some say that doctor-aided death is widespread already, only covertly, and that the Netherlands is a model of how to establish the right to die by bringing the practice out in the open, where the medical and legal system can oversee it. This issue is similar to how abortion was seen before it was legalized. The main reason for legalization of abortion was because it was being done anyway. People had access to abortion, it was just being done terribly. We're in exactly the same situation today: People have access to assisted suicide; it's just being done so badly.
