So, the internal struggle to help out... well done. But, why try to help a person out, then turn around and kill his kid later? Unless it was supposed to be a "mercy killing." But, I don't know if I can believe that. After all, while he did a very quick assessment of the kid, he didn't really know how wounded he was. And second, the character showed very little remorse about killing the kid. He seemed (slightly) more upset about not being able to help out the father. If the main character is supposed to be "evil", then they should own it: Have him go in and look for supplies without bothering to check the condition of the father. Maybe it comes out better as a written story, where the author can tell the reader what is going on in the characters' heads.
