The Outcast of PokerFlat

If you had to blame someone or something or the outcasts' deaths, who/what would you blame & why?

I woulod blame Bad Luck because the whole thing started with bad luck. What happened in PokerFlat when they were going to kick out all the bad people, that was pure bad luck to them becuase they agreed to it. When they found Tommy and Pinty that was bad luck to them because they were on their way to PokerFlat but they runned into the outcasts.If they never had bumpt into eachother they wouldn't have died and would just be on their way. Also, when Unckle Billy left with all their horses that proved bad luck to all in the cabin because they were tranded there. When the snow storm came right at the same day they slept there. Then the final prof of bad luck is when Tommy was too late with the help and found everyone dead.
