Regarding the plan involving Locken, there are several drawbacks. Firstly, we might be targeted and killed, or otherwise outsmarted. Secondly, our already strained relationship with Ninsharia is unlikely to improve. And thirdly, we'll gain a reputation as dishonorable scoundrels worldwide. Although, there's an interesting and debatable point about reputation: it could be argued that, on the contrary, we'll gain a reputation as decent guys, something like, "Hey, no hard feelings, it was just business. We freed the target, and you can have the rest." I forgot the third point.
Where do we end up when we save the world?
