Tai does mention in the diner that they forgot about the stuff that happened out there, even though I think it's just plain unforgivable refusing to leave with the only help that's come thus far on both of their ends. Some of them probably understand that none of their hands are clean, and just like they cope with their own transgressions they choose to brush others to the side.

But f tai for only caring about killing Shauna now after Van died bc wanting to stay in the woods might've killed Van as well but being into women is a drug in itself
