What are the traits that bring samurai closer to European knights?

Knights, like samurai, have many similarities. Both those and others fought for their master. In addition, knights and samurai professed their codes. For samurai it was “Bushido” or, in other words, the path of a warrior, every samurai inherited it and strictly followed all his rules, including death for fleeing from the battlefield. The knights adhered to their “code of honor”, the main idea of which was the fight for justice and the protection of the innocent.
