Worst. Father. Ever.
Wow talk about a terrible father, he hooks up with a former cult member whos obviously screwed up, then takes his kids along with her out in the middle of nowhere in the snow to a cabin, then leaves his two kids alone with this mentally unstable former cult member for days.
I mean in what world would any sane rational father do this? Then surprise surprise he comes back and shes lost her mind and ends up killing all of them.
