Yes, voluntary euthanasia is legal in some places and when it is carefully and compassionately regulated, it could be an option for individuals who are suffering from great physical pain that will not subside. It is a very controversial issue, but when approached with compassion and love, it can be made legal in a way that only very few people will actually have a need for it.
Yes, voluntary euthanasia should be legal because sometimes the pain is to much to bear for some people. If a person is in tremendous pain or their quality of life will not get better, they should be able to end their life the way they want. The decision should be up to the person, no one else. The law should not decide what a person can do in this situation.
Although some of these people may be sick, it's ultimately their opinion if they want to die or not. Now it is true that some may not be able to make their own decision (which is why some people may disagree and question this debate). However, if at the time voluntary eunthenasia is performed is illegal, then it should be prosecuted.
Although to some people voluntary euthanasia may seem no better than needless suicide, when offered as an option to patients who are terminally ill and in terrible pain, it can provide a way to die with dignity and on their own terms. It is far crueler to force someone to live out an indeterminate number of days with an incurable, terminal illness causing them great suffering than it is to allow them to make this final decision for themselves.
