ELI5: Why have so many cultures developed the concept of honour? A fair fight cuts down chances of survival.

No one wants to die in a horrible, unpredictable way regardless of what culture you're from.  By making a code of honor, you force conflicts into the public and expose people to ridicule or consequence.  It takes the reward out of being sneaky or unfair, so it tries to force combat on an even level as opposed to who can be the most horrible first.
