It's Dutch. Literally "little winter king" which is the word for "wren" (the bird, also my name).

At the same time, it generally doesn't benefit one to commit suicide and so it's not like there'd be waves of people doing it without the stigma. As for the ethics of euthanasia, I think that only becomes an ethical question because of the fear and stigma associated with death. If a person requested to die because of their misery (whether by their own hand or another's, to assuage the issue of "murder") I don't see how there can be an issue if there is no ill in death.
