Why did they kill the guy at the end?
I don't get why they killed the guy at the end. He was his brother-in-law right? Everyone else had some or little reason to be killed but why kill his brother-in-law? He was never bad to Jamie as far as I saw. Was it just that at that point they were doing it for thrills? I know they killed the dim witted kid for thrills in a way but he had a "defect" so they had a reason. Sorry if I missed something. I tend to stop and start my movies like when I get hungry and stuff.
Thanks
