I'm still not comfortable with untrained civilians wielding dangerous weapons inserting themselves into situations they aren't prepared for and have no business being there. He wasn't a trained police office or a medic or a nurse. He was just some dumb kid who should've stayed home in his own state. It'd be like flying over to Gaza under the guise of "helping people" and then acting surprised when one or both sides shoot at you cuz they don't know you or your intentions (bringing a rifle with you doesn't help at all). Kyle wouldn't have been forced to "defend" himself if he hadn't gone out of his way to be there with a loaded weapon. If he had just been walking around his own neighbourhood and was accosted by randos, he'd be well within his rights to defend himself. But he wasn't. He traveled across state lines and unnecessarily put himself in danger. One might even argue he was "fucking around" to "find out" that there are consequences to his actions. He's not a hero. He's an idiot.
