Just because soldiers are on the same side right now doesn't mean they always will be. Having personal feelings about your comrades is one the worst sins you can commit. Politics determine who you face on the battlefield. And politics are a living thing. They change along with the times. Yesterday's good might be tomorrow's evil. People's values change over time. And so do the leaders of a country. So there's no such thing as an enemy in absolute terms. The enemies we fight are only in relative terms, constantly changing with the times. Sooner or later, your conscience is going to bother you. In the end, you have to choose whether you're going to live as a soldier, or just another man with a gun. Which will it be, Jack? Loyalty to your country, or loyalty to me? Your country, or your old mentor? The mission, or your beliefs? Your duty to your unit, or your personal feelings? You don't know the truth yet. But sooner or later you'll have to choose.
