Humans bonds are very strong, especially with the beings that fought by their side, Humans or not. They will go to great lengths to aid or protect them from harms, from deviating their journey to engage into violence, even against a government
H : So, you send my buddy Torkk here to fight by our side on the cluster fuck that were the Tyrant wars, for the sole purpose of his death will bring honor and glory to you. But he being the killer machine he is, collecting the highest awards our military have to offer and not dying is somehow a problem ?
A : YES !! We demand that he cease his life at once, just looking at him disgust me. He was ordered to die and didn't do it. Can't follow a simple order. This is of no matter or concern to you
H : Well... That certainly a point of view. But you see, Torkk fought by our side, bleed by our side and many guys out there are still alive because of him. So we disagree with the whole "he must take his own life" shenanigan. Just send him and his clan to us, we will take care of them and they will not bother you.
A : AH ! How dare you address me, we read the reports : you helped him to stay alive. Like him, you got no honor nor glory. We stand by what we said : he must die
H : Ok, diplomacy failed. You heard the guy. This is now a hostile take back. Deploy the drop ships. All guns are clear. They want honor by death ? Happy to oblige. Torkk, my guy, hang on : we are coming for you
