The Outcasts of Poker Flat

If you had to blame someone or something for the outcasts' deaths, who/what would you blame & why?
-Uncle Billy
-citizens of poker flat
-bad luck
-outcasts

I think that the one that you need to blame was uncle billy because if uncle billy hadn't of run off with the horse all of them would of have a chance of living because they wouldn't of got tired and stop walking to stay in that little hut that they stayed in and where some of them died in. I think that uncle billy was selfish because if uncle billy could of woke them up and they wouldn't of got caught in the snow storm that badly. That's why i think who you should blame for all of the things that were happening to them.
