We are in an age where the warrior is not as he was. No longer can a man choose his battles or his lord. The battle is as much one of the will as one of war- different warriors excel in each.
Is a warrior of will any less than a soldier in an army? A warrior of will at least is always accountable to himself. The soldier has a job to do and must fulfil it or be tried for treason- agreement with the cause is not an option in today’s armed forces.
There can be no just war where both sides believe that god is on their side- or perhaps the battle. What if that god is one whom benefits from the harvest of the battle fallen.
