The German word for suicide is Selbstmord, "self-murder". It's being used less and less nowadays for the same reason, as murder implies malicious intent. People opt for the neutral term Suizid instead.

Which is great except we still use the German word for "commit" with it when talking about it. I didn't realize that until reading your comment. So we only did half the thing we were intending to do and I never noticed. 😅
