At least with western equivalents, we have more of a chance of understanding each other.
Even with western equivalents it may not be possible to reach a consensus since there are multiple western honor codes.
For example the code of chivalry that the knights followed differed depending upon era:
The first few codes were obey the church, defend the church, fear god, etc... which no longer really apply to modern civilization.
800 ad had at least two separate codes and many people argue as to what is and isn't honorable even know:
Code 1 Charlemagne's Code of Chivalry, listed the knight's duties:
To fear God and maintain His Church
To serve the liege lord in valour and faith
To protect the weak and defenceless
To give succour to widows and orphans
To refrain from the wanton giving of offence
To live by honour and for glory
To despise pecuniary reward
To fight for the welfare of all
To obey those placed in authority
To guard the honour of fellow knights
To eschew unfairness, meanness and deceit
To keep faith
At all times to speak the truth
To persevere to the end in any enterprise begun
To respect the honour of women
Never to refuse a challenge from an equal
Never to turn the back upon a foe.
Code 2:
Love God Almighty with all your heart and all your powers
Love your neighbour as yourself
Give alms to the poor as ye are able
Entertain strangers
Visit the sick
Be merciful to prisoners
Do ill to no man, nor consent unto such as do, for the receiver is as bad as the thief
Forgive as ye hope to be forgiven
Redeem the captive
Help the oppressed
Defend the cause of the widow and orphan
Render righteous judgement
Do not consent to any wrong
Persevere not in wrath
Shun excess in eating and drinking
Be humble and kind
Serve your liege lord faithfully
Do not steal
Do not perjure yourself, nor let others do so
Envy, hatred and violence separate men from the Kingdom of God
Defend the Church and promote her cause.
Which honor code would we use?
Religious ones like the Ten Commandments, Noahide Laws (seven laws of Noah-Jewish), Eight Precepts (Buddhist).
Rules of engagement? Such as British Military ROE or U.S. Military ROE.
Codes of Chivalry?
One of the Pirate codes (Captain John Phillips's articles or Bartholomew Roberts's articles), Cowboy codes (there are several), or doctor codes (Hippocratic oath, Code of medical ethics)?
Ancient Greek concept of honor (respect which was due according to one's reputation and rank).
There are a lot of western codes of conduct and they are not all the same or valid in all situations. Also what constitute as honorable to one person may not be honorable by another persons definition of honor. In some cultures (that are western), honor killing of females of one's own family are considered justified if the individuals have "defiled the family's honor" by marrying against the family's wishes, or even by being the victims of rape.
Last I checked, there's no moral or social code that's in use today which says those things are okay to do.
There are a few. There are several in which the victim of Rape is considered unclean and has considerable social stigma such as not being allowed into schools. In some of those very same cultures the rapist gets basically a slap on the wrist. For instance a 12 year old girl was raped by 4 guys according to Maldivian news and it was deamed consensual even though they broke into her room with an axe (July 22 2007). In Zimbabwe training camps they are taught to rape, maim, torture, and kill for instance in 2001 they kidnapped a 20 year old and an 11 year old girl and raped and tortured them for over 6 months and that is just one incident there were 100's of people who had it happen to them (It was socially acceptable). In april 2005 a newly married women was raped by three males in Pakistan with the consent of her in-laws who saw it as an honorable revenge.
