Context: in this manga, an ex boxer now working for a yakuza group has just attended the funeral of his boss (組長). After the funeral, he sits alone and watches his pinkie. Then thinks:
何考えてんだ俺は… あめェよ… 命【たま】かけなきゃならねェ世界【とこ】で生かされてんだ。あめェよ… 小指じゃ命につりあわねェっての。
In the manga the word 世界 is often used to refer to the boxing world, and I think in this case too. I understand that he is talking about the yubitsume ritual, but the meaning of the last sentence is not clear to me, the verb in particular. I think it literally means "a pinkie can't match life", but what does he actually mean by that? What is the general meaning of the whole sentence? Also, why 命 has たま as furigana? My attempt:
What the hell am I thinking? I'm so naive... I am forced to live in a world where you have to risk your life. I'm so naive... a pinkie can't be compared to life.
Unfortunately, the manga doesn't provide much context because it focuses on the boxing part, this is just a minor scene. I don't know why he thinks about cutting his finger, maybe he feels guilty about the death of his boss?
Thank you for your help!
EDIT: maybe my explanation wasn't clear, but in the end he doesn't cut his finger. Here you can see the page in question (page 29) and some pages before it. In the first page, you can see an unknown member of the yakuza clan with his amputated pinkie. This is all the context the manga provides, after these pages it goes back to the main story.
