I have listened to it and checked the transcripts and he said every single living person.. That I am sure of..

What I thought sounded funny is he say that if the people from the Freighter make it to the island every single living person would be killed.. Isn't it implyed that if they could be killed they were living. It sounded really odd to me the way he said it.. It caught my attention..
