Once upon a time, I had a nauseous feeling in my guts, so I only ate half of my rations. I was kinda glad, because after we got through slaughtering a wretched xenos, I lost my nerve and threw up what I'd eaten.
So much blood. Too much burnt Tau flesh. Seeing my fellow guardsmen cut down by their cowardly tactics. It was too much for me to bear.
But then I spotted a single, young Tau, possibly male. Something foreign welled up in my heart. I think the minor illness that had been interrupting my ability to serve the Emperor made me delirious. I thought of my own son, back on Terra Prime. The small Tau cowered, hidden from the view of everyone there. It looked so terrified and thin. I couldn't take it anymore. I approached it, fetching the rations that I hadn't eaten from my pack. It withdrew and started to shriek, but I put a finger over my lips and shushed it. The wretched xenos seemed to understand and stared at me in a cross between fear and resignation. I reached the creature and offered it the food.
The Tau gave me back an unreadable expression, then began eating. Biscuit, part of some beans, a piece of sandwich... and the eating utensil that was part of the ration. Still delirious, I could only watch in mild amusement as the young Tau got part of the spoon down its throat and slowly choked to death. I laughed. Emperor protect me, I laughed at the death of this wretched xenos. I laughed until I cried, the realization of what I'd done finally sinking in.
I had wasted the general issue meal that had been assigned to me, when a simple shot from my lasgun would have sufficed.
I am so, very, unequivocally sorry.
