I don't understand な in this sentence


まだ何度でも食べたいと 欲張ってしまうな

So I know an imperative negative like 飲むな means don't drink, but in this case
the speaker is talking about himself and his inability to not stop his own
desire. why is this not 欲張ってしまわない instead of 欲張ってしまうな.

Thank You!




な can also be a sentence-ending particle, having relatively the same meaning
as ね sentence-ending particle except having a bit tougher or manlier nuance as
books usually like to call it.
