Answer:
Yes, he should forgive himself for his failure to save his best friend K frm the typhoon.
Explanation:
"The Seventh Man" by Japanese writer Haruki Murakami tells the regret story of how the narrator lost his friend. The story revolves around the theme of redemption and the need to accept fate, which none can do anything about.
The narrator should forgive himself for what had happened to his best friend K. He knows that K died due to his refusal to turn back and help him during the typhoon. He even admits "I told myself to run over to K., grab hold of him and get out of there... I found myself running the other way." But he also knows the dangers of his acts if he was to save him. It could kill him, either its his life or K's life. And he decided to save himself in the end. This regret and remorse in not being able to help save K made up almost the whole plot of the story, but then again, he also keeps himself reminded of the need to forgive himself. He had been suffering from guilt all these years, "I might have been making terrible mistakes all those years", but now he needed to let it all go. Everyone of us makes mistakes in our lives and we learn from them. Likewise, he needs to have redemption from the past, and move on in peace.
