My problem lies with how Sakamoto is pretty much alive and unscathed at this point.

I would argue that one doesn't regress to killing because they can (no police around), but because it's necessary for ensuring survival. It's fine to try put morals into your decision making if you want to, but for doing so it should also put your life at more risk.

I was pissed off that Sakamoto was allowed so much time to think about his first kill, but somehow survived because his opponent was abysmally bad.

Later on when Sakamoto battles the kid (who wasn't abysmally bad), the writers couldn't use that trick again. Sakamoto had to either fight or die, but they wanted to keep him "pure", "morally good" and what not.. so they used amnesia/delusion as an excuse for the "immoral" behaviour that was necessary for his survival.
