----------------------- SPOILERS -----------------------
Right I've got to decide who to kill but, I'm not sure who. I'm swaying towards Derrick as he's a junky and it would be better for him as he will never turn his life around, but he has the longest drive to his grave.
Killing Francis means its a shorter drive to the grave and I would sway towards him as he's killing his brother but then your also taking away the only "sucessful" (lossely used as he's a bent copper) McReary from their mum.
Also if Francis stays alive you can still call him but I'm not sure why or what he would provide from the game if kept alive.
Either way I like what thi8s mission is doing as its making you choose and its also shaking up the story as your with Kate and good friends with Packie.
Anyways what did you do and did it help the rest of the story in anyway, please keep further spoilers from later on in the story to a minimum please.
