fatal
Ending in death
Fatal means causing death or destruction: a fatal accident, a fatal disease, a fatal blow.
The word extends to anything that causes ruin or failure: a fatal flaw, a fatal error, a fatal mistake.
Something fatal is decisive in a way that can't be undone—the consequences are final and irreversible.
