Broken Perspective pt 1

Some people would call Jack Harkness a broken man - but I know better. I've seen him grow from a disillusioned conman into a defender of Earth, through trials most people couldn't imagine. He's survived, and thrived, and built an institution which will protect the human race until it is ready to protect itself. As much as I disapprove of their methods at times, saving the Earth...who can argue with that? Well, the Master. And the Sontarans. Maybe the Nestine... Daleks... Cybermen... Sycorax... Raknoss... Ice Warriors... Okay so a lot of people would argue about that, but it's not like it's their planet is it? Oh, well, no, it's not mine either technically, but I like to think of myself as a sort of honorary Earthling...Earthman? Earthian? What is the correct term for someone from Earth who isn't human anyway? No, never mind, not the point. What was the point again? Oh yes! Jack. No, Jack isn't a broken man, of course not. Why would you even suggest it?
