Dirty tricks are a part of the mercenary trade. No unit can stay ‘clean’ forever, and sooner or later you’re going to have to do something a little dubious to get your way. And sometimes, it actually ends up that you’re doing the right thing, even if you’re going about it in the least ethical ways possible.
Case in point, what we did to Devon Wainwright. We’d had concerns about him ever since we landed on Ashburton, based on the information we’d been provided on his family’s involvement with the pirates. He had a clear motivation too; overthrow the government and restore the planetary monarchy with his family at the top, and go back to how things had been for the last few hundred years before the Jihad.
