Yes and hopefully it would be a cultural turning point to offering it to non-criminals in hopeless and painful circumstances. I don't agree with this "euthanise for any reason" thing. If the government or some other organisation is offering the service, they have a burden of due diligence with respect to soundness of mind or a determination of suffering and so on. No questions asked suicide centres seem like a bad idea, even if they are a logical extension of our philosophical first principles. Manic depressives would be in big trouble, for example.
As for the method of euthanasia, I never understand why we don't use helium hypoxia. It seems completely peaceful and reliable. It is the suicide method of choice for doctors... the Hopkins pervert gyno killed himself that way. It is a non-toxic except when breathed in the absence of oxygen, and produced no feeling of smothering, as I understand it.
