That Is What You Are Best Suited For, After All.
The superhuman killer might have been in the army, but he knew exactly what he was. He was only a slave that the army was trying their hardest to keep on a leash! He was a guard dog that they would send out whenever they felt like it and when he came back they would throw him a bone and pet his head before tying him up again like an animal! It grated on his nerves and he hated the fact that this was his life. As time went on, he started to grow a distaste for killing people. Killing normal people became so easy and simple to him that there was no fun in it anymore.
