Metaphorical meaning of 買う


Context: in the manga
[Rikudou](https://ja.wikipedia.org/wiki/%E3%83%AA%E3%82%AF%E3%83%89%E3%82%A6),
Riku follows his trainer risky instructions in order to win (the trainer had
told him to take a lot of punches in order to understand his opponent's
fighting style). When, after risking his life, Riku is finally going to land a
punch, his opponent thinks:

> 許す  
>  打たせてやるよ  
>  勝つために他人【セコンド】に自分の命全部投資出来る  
>  お前の覚悟…  
>  **買って** やる！！

What is the meaning of 買う in this case? My guess is that the opponent is
envious of Riku's determination end wants to "acquire" it himself by letting
him beat him. Is it correct?

買う sometimes means "to appreciate (someone's trait)", "to value", etc. It has
nothing to do with purchasing.

As is the case in your example, it's commonly used in decision-making contexts
(e.g., やる気を買って彼を採用する, 難しい選択ですが彼の将来性を買いましょう). This お前の覚悟(を)買ってやる also implies
the spaker made some decision (apparently "taking Riku's punches
intentionally"?)
