Honor is all about trust and integrity. It's a bedrock for any group of people because without it there is no trust or justice. I strongly believe that every organization should have an honor code that charges every person with monitoring the group to ensure that honor is never breached and, if it is, to root it out. A community of trust is essential to great organizations. To lead you must have mental toughness to make difficult decisions.
Leaders stick with the team.
Loyalty is essential if you expect to succeed. Just like marriage or any institution, endurance and commitment of each other to the union is essential. If leaders jump ship every time a better looking deal comes along, imagine the chaos that results and the souls that are lost along the way. Now, loyalty need not be blind. Strong institutions must question underlying assumptions, but commitment must also be a bedrock value.
