If you were in the Armed Forces would you be willing to defend a fellow soldier that you would normally discriminate against.
I would because we would be in a war. I may not agree with what they think is right or what they believe in, but we would be on the same side so I would attempt to protect them. I would do it because it would be the right thing to do and in the future if I would need help there is a greater chance that they would help me. Besides those who forget the rules of the battle field are scum, but those who leave a fellow soldier in need behind are worse than scum.
