How do you make a haiku on samurai?

Well first, ordinarily, haikus are about nature, so i'm not sure if there is one about samurai. But first, think about the sole elements about samurai. What drives them, what's important to them etc. Remember, there are three lines, the first one has 5 syllables, the second one has 7 syllables, and the third one also has 5 lines. So here's something I might write:

Samurai are skilled

with great talents with a sWord

their honor binds them.

Okay, I know, not the best thing you've ever read in your life, but you want something along those lines.
