Critter really hates humans... When you read the diary pages it kinda makes sense why in a crazy way.

I mean it's not their fault they got trapped in the snow and they needed to kill all the bunnies to survive, but the wolves needed food too. So assuming they ate that kid, they didn't do it to be jerks. I mean they even went after the oxen first, wolves only really go after humans when they're desperate right?

It's only after they killed the wolves that Critter showed up. It keeps saying it's not about revenge though so it has to be something else.
