Regarding (1), you mentioned in another response the value for human dignity as a reason against euthanasia. But medicine has advanced to the point where we're able to keep a human body alive regardless of whether or not the human person has any sense of dignity. The grandparent comment is an example of such a scenario.

>"suicide is better than living like that" - well... yeah, but isn't that always the motive, what's the difference now?

The difference is that the person and their medical personnel are in agreement that realistically: there is not a reasonable hope that their medical condition(s) may be cured or alleviated, so the overwhelming likelihood is that they are going to die from their medical condition(s), and their experience leading up to their death is going to be agonizing and severely depriving of dignity.

With suicide, a person is choosing to take their own life even though they don't have a medical consensus with a reasonable expectation that they are going to die of any condition (besides old age--which I don't believe is commonly a major factor in suicides and would probably not be acceptable).
