I'm going to confess to the sin I committed during the war.

Viet is incapable of making mistakes. For Viet, nothing is impossible.
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means crime and the verb vocab version can mean to commit a crime, to make a mistake, or to rape, depending on the context.
You go to commit a crime. How did it go, you think? Well, I thought it went okay (おか). Imagine yourself committing a crime and it going just okay. Not great, not bad... meh. Okay.
