No one is forced to take part in voluntary assisted dying – neither the dying patient nor the medical professionals who care for them. Medical professionals can refuse to participate in VAD due to moral or ethical convictions without sanction or criticism. Similarly, anyone with religious views that run counter to VAD can conscientiously object – in this way VAD laws respect religious freedom. At the same time a patient's right not to have those religious beliefs imposed upon them is also respected.
If you don't approve of VAD, don't take part it in it. It's that simple.
