And this is exactly why I don't write character meta-analysis, haha.Personally, I think Harry is sharp enough and doesn't react so absolutely with his heart such that he would know that it the rounds in the gun were blanks. Eggsy is different from Harry in that regard - Eggsy does react very emotionally to the final test, as we can see in the film; that's ultimately part of why he fails the test. Harry, conversely, can emotionally divorce himself from the task at hand to complete said task. That's apparently something Kingsman values in agents - that and absolute loyalty, I can't imagine the test being about anything other than those two things, given the nature of it. But really, as soon as I saw those dogs on-screen I knew the recruits would be asked to do something like the final test. I'd think Harry would cotton on to it, too.What I actually said in my meta was, "It’s strength and power used not for the sake of strength and power; Harry’s not a bully, or a tyrant. He doesn’t kill senselessly*, and I’m sure he wouldn’t follow an order that he considered to be pointless murder had Arthur given him one without reason." What I meant to emphasize was that Harry's not corrupt with power; he doesn't use his strength like Dean, to push people around for the fun of it. He uses his strength and discipline to make a difference; that's another thing he and Eggsy have in common.In the film, it's Eggsy who sees shooting his own dog as a senseless killing of something innocent, something he is emotionally attached to. Whether Harry realizes the truth behind the test or not, there IS a point to completing the test, it's not quite senseless or pointless - the point is that it's a test, another obstacle between Harry (and Eggsy) and knighthood. In that light, I can see Harry shooting his dog - especially a younger Harry who hasn't the years of confidence and experience to back up his decisions, a Harry that doesn't yet know himself well enough or doesn't yet have the confidence to stand up to Chester King as he does in the movie.And don't assume that it was easy for Harry to shoot Mr Pickle - we only see Eggsy failing the test, we know nothing of Harry completing his besides the fact he passed it. Harry could have initially resisted; he could have cried but done it anyways because that is how badly he wanted Kingsman. He could have done it quickly, if he had realized the truth behind the test. We don't know any of it, so it's hard to say.Those are just a few thoughts on it; obviously, there are different ways of reading Harry's character, and this is just one of them.
