Is the recording of a person's last words reliable?

Context: A person's last words, their final articulated words stated prior to death or as death approaches, are often recorded because of the decedent's fame, but sometimes because of interest in the statement itself. Last words may be recorded accurately, or, for a variety of reasons, may not. Reasons can include simple error or deliberate intent. Even if reported wrongly, putative last words can constitute an important part of the perceived historical records or demonstration of cultural attitudes toward death at the time.

Answer: Sometimes it is, while other times it may contain errors or deliberately misquoted.
