"I'm a weapon," the Soldier explains patiently, and without any particular distress at the words. Maybe some regret that they have to tell yet another person who's probably not going to take it well. (One of these days, you're gonna actually stop telling people. Not gonna let anyone get the wrong idea, Sergeant.) "I take orders, I have handlers, get worked on by technicians. Like you said, like your world's Heartless-- emptied out. Except I only kill what I'm told to kill."
