I don't think that's the problem with euthanasia laws (at least from my perspective) - if somebody makes a free and informed choice, without pressure from family, carers or finances, to end their life, they should be able to do so with society's help. That could, however, easily end with people feeling expected or pressured into doing this so as to not feel like a burden, which would be a bad thing. There's also the argument that most people who feel that life is not worth living could be persuaded otherwise if we were more energetic about improving their care. In summary, the issue isn't that some people should be allowed to be helped to die: the issue is that we can't agree on how to design a law that caters to those people while avoiding serious abuses of the system.
