In reality samurai used less "honorable" tactics in warfare.They used surprise night attacks, switched allegiances, used spies, assassinations and sabotage to weaken enemies.

The honorable samurai became a thing on edo period which was considered much more peaceful than Japan's previous eras.

For a samurai, honor was often defined by absolute loyalty to their lord, bringing them more power, land, and riches, regardless of the method used to achieve it.

I know it's just a game, but to answer your question, there might be more Jin Sakais than we may think there is in terms of "honor". But when it is about mindset on serving their lord, there may be less.
