Jin's uncle represents an impossible, fantasy version of honor and their code. As mentioned above, it's exaggerated to the extremes and real samurai clans had zero issue doing literally anything Jin could think of in-game.

If his actions harmed the invaders, won back territory, minimized samurai and clan deaths and kept their regional stability (see: dgaf about the villages) he'd have been a mystical figure of importance to them. They used their codes and laws to be, at best, neutral and at worst much like a crime syndicate of today. Honor and all that bent to excuse their actions. Jin's uncle should have been bouncing up and down in his fort in joy.
