This is an incredibly solid comic. When I read Joe Kelly's Deadpool run from the 90s, I was surprised at how much angst the character had (not to mention how genuinely terrifying he could be, and it still kind of work). He ends up having enough character depth to support a fair number of stories, even if the series wore on me eventually.
In this one, the surprise is Cable. Cable is a more interesting character than he gets credit for, with his reputation for being Deadpool's sort of stiff/straight man buddy cop. Here he shows his heart, and in many ways his trauma-earned stupidity. He thinks of things as a soldier, but realizes that he wants to leave a more lasting mark on the world than that. His plan is painfully sweet and misguided, like a 16 year old playing god. He has no skill in this arena, and it costs him. There are no last minute revelations of a secret plan like you'd see in a comic about a great leader. Just a man who fails.
In the end, Deadpool saves him because Deadpool likes him. The two are left a pair of characters who hardly fit into the world around them, who both say they desperately want to stop fighting but only really know how to solve problems with their fists. Whatever they want to do, it looks like they'll be figuring it out together.
