Running away is always an option, as long as you don't abandon allies or people you need to protect. Honor in battle, fighting spirit etc. aren't important at all. They just contribute to the everlasting cycle of violence, followed by revenge followed by more revenge, and all this fighting does is endanger the civil populace.
And out of an oppressed populace, everyone who is strong in any way will rise up to take power for himself, and oppress even more people.
All of you are part of the problem with your thirst for more and more power. The physically strong shouldn't rule this world! There are more ways to be strong. Nurses see death every day and yet they continue, firefighters jump into burning buildings to save people, every mothers love for their children is stronger than any yonkou could ever be. That is the kind of strength that should rule this society.
