Have you watched Kingsman? They also have the same method of testing the loyalty of their recruits in the film- training with a dog while it's still a puppy and shooting them as the last test. Except they gave the recruits blanks. Maybe they're trying to find out how far can you kill to prove you can kill for them. I do agree it's fucked up tho, there should be a warning at the beginning of the chapter.
Image playing around out side and, your best friend that you spent most of your life with, just shoots a bullet through your body. This is fucked up, at least put a warning.
