Honor is living up to (your) personal moral code.
Everyone has their (own) principles or honor code they live by.
Example: "If I say I'm going to do something I will do it." might be one. However every practical person knows human beings make mistakes! Wallowing in guilt and "shame" doesn't change the past.
Therefore taking one's life because they weren't able to be their "ideal self" is a ridiculous action. No one lives long without having failed at times to live up to their expectations.
Taking oneself too seriously and expecting "perfection" leads to severe depression when life throws it's inevitable curves. You have to learn to evolve and ride the waves.
You have to be able to "forgive" yourself in order to love yourself.
Sadly a lot of people are not in control of their own beliefs.
In some parts of the world "individuality" is discouraged. Their culture and elders (determine) what your "honor" and "morals" are. If the individual can't live up to (their expectations) or is made to feel like a "failure" this could make them suicidal.
Life is a (personal) journey.
Don't let other people (tell you) how to live (your) life!
You're entitled to have (your own) moral code and honor system.
Accept the fact that you are a human being and will make mistakes.
