"Do what is right, not what you think the high headquarters wants or what you think will make you look good." --General H. Norman Schwarzkopf
If you ask me, an attitude like that can't lead one down a wrong path. It will certainly keep one's conscience clear.
In Flank Hawk, and in the current work in process (Blood Sword), when writing Krish and his actions, doing what is right, what friendship and loyalty demands--at least as he sees it--is what guides him.
I think that's a main reason why readers enjoy Krish's story and it's why characters in the novel trust him.
