He would surpass all the powerful people and eventually stand at the peak of the Ninja Realm. There was no right or wrong, no good or evil. In the end, it was all for survival. Survival was the first rule of the protagonist. The main character only has one wife, and definitely not a harem is the second rule of the book.
