Milo aunty actually got ask before back in 2008:

My guess is that they will legalize it only when it becomes more widely adopted/accepted and ways to regulate this has matured enough.
Euthanization (doctors actively killing their patients) and assisted suicide (doctors just passively helping patients to do so) are subjects that have long been debated globally and the decision isn't easy.
Even now, a good portion of doctors themselves will feel such a law by governments will force them to break the Hippocratic oath they took.
"I will use those dietary regimens which will benefit my patients according to my greatest ability and judgement, and I
will do no harm or injustice to them".
Through the years, we have seen valid reasons for patients who wish to undergo euthanization. A few of the main reasons:
- the pain patients have to continue to suffer. The patients and often their loved ones cannot bear to see the patient continue to suffer
- monetary/emotional burden to the patient and their families
- no chance of recovery
There's way to deal with all the above without resorting to killing the patient. Whether is it more humane or acceptable depends on how people look at it.
For pain, there's painkillers.
For monetary means, healthcare should never reject patients even if they cannot pay in the first place. There are state and private charities or crowdfunding that can help.
For hope of recovery, what if after the doctors pull the plug today, then tomorrow someone announces they've found a cure?
If these concerns can be addressed, is it still justifiable to euthanize the patient?
Another consideration is that it opens up the possibility of misue. We generally trust doctors, but as seen from inflated medical insurance costs, there will be healthcare facilities (the hospital management who are looking to make more profits for example) who will misuse this and recommend unneccesary treatments for money.
Many institutes have updated the Hippocratic Oath to match with modern times/requirements.
However, the danger is akin to removing/changing the first law of robotics:
"A robot may not injure a human being or, through inaction, allow a human being to come to harm".
It will open another can of worms and provide opportunities of misuse. There are very evil people out there.
