In this YouTube video from an anime [暗殺教室 渚 殺気②
t=44s](https://www.youtube.com/watch?v=bFuiax-2QRU&t=44) what I hear the
character is saying is the following:

> 戦{たたか}って勝{か}たな **くたって** いい、殺{ころ}せば勝｛か｝ちなんだ。

I don't understand where the part in bold comes from.

I would guess that it is some variation of the following sentence, but with
some additional nuance.

> 戦って勝たなくていい、殺せば勝ちなんだ。
