In our modern world, we look unkindly on mistakes and imperfection. But this is far from the samurai ideal. Mistakes are part of the learning process and if you haven't made them then you are, indeed, dangerous because it means you have never learned anything. Mistakes, to a samurai, are the proof of your learning.

Being a samurai is all about selfless service and if the lord abuses the servant, it is no longer a situation of service; it becomes the situation of a victim. It is never acceptable for a samurai to be a victim. It is never acceptable to allow a lord to abuse you or rob you of your dignity. In such a situation, it is acceptable to walk away.

A samurai chooses to serve a master and does it out of respect and love, not because they are forced. Service to them is not demeaning; service is an expression of their prowess and their pride; they serve because only they are strong enough to serve with such flawless perfection and such consummate ability. It is a source of pride to them.

Life in Japan, nowadays, is nothing like a Kurosawa movie, and only the contemptible Weeaboo thinks that it is. In order to be a whole, well-rounded Otaku, you need to be up on Japanese popular culture, as much as you may be up on anime, samurai philosophy or the canon of Square Enix games.
