I am, and this may be surprising given my personality, someone who believes that almost anyone can redeem themselves and realize the error of their ways, no matter how awful they used to be. I think our problem, and I’ll presume to speak for Frink here, is that people who have caused far less harm are not forgiven purely because they didn’t worship the right deity while a Hitler or a Manson could make it to heaven if they just believed in God at the last second. Even if Hitler really felt horrible about what he did and wanted to somehow (as absurd as this hypothetical is) make amends for what he did, he’d still go to hell unless he believed in the specific deity that he needed to.
