Courageous. I'm not sure about where patriotism falls into that. Answering a higher moral code rarely has to do with patriotism, I think.
I believe it's cowardly to allow yourself to remain in a situation where you have to kill people for an immoral reason.
I don't know if you are familiar with Camilo Mejia, I spent a week with him (and others), and have a tremendous amount of respect for him. I found his letter from prison (Regaining My Humanity) to be particularly powerful.
Many have called me a coward, others have called me a hero. I believe I can be found somewhere in the middle. To those who have called me a hero, I say that I don’t believe in heroes, but I believe that ordinary people can do extraordinary things.
To those who have called me a coward I say that they are wrong, and that without knowing it, they are also right. They are wrong when they think that I left the war for fear of being killed. I admit that fear was there, but there was also the fear of killing innocent people, the fear of putting myself in a position where to survive means to kill, there was the fear of losing my soul in the process of saving my body, the fear of losing myself to my daughter, to the people who love me, to the man I used to be, the man I wanted to be. I was afraid of waking up one morning to realize my humanity had abandoned me.

and to conspire was my duty to the people;
I would have been a criminal had I not.
I am guilty, though not the way you think,
I should have done my duty sooner, I was wrong,
I should have called evil more clearly by its name
I hesitated to condemn it for far too long.
I now accuse myself within my heart:
I have betrayed my conscience far too long
I have deceived myself and fellow man.
I knew the course of evil from the start
My warning was not loud nor clear enough!
Today I know what I was guilty of…
