Minor spoilers - Are we supposed to ultimately feel sorry for Bill Pullman's character?

Hi, granted, this movie doesn't reveal 100% if he was guilty of his wife's murder but we, in a way, assume he was and given what we see afterwards including his sense of guilt over it, suffering, him imagining he is someone else (I sort of interpreted this film as being much of what happens in his mind) etc, I sort of wonder, as an audience, even knowing that he IS guilty of his wife Renee's murder, are we supposed to feel sorry for him?

Because unlike say some obvious villains in Lynch's movies like Frank Booth in "Blue Velvet" (1986) (his greatest and most perfect 10/10 achievement) and even that gangster guy Dick Laurent here whom we are somewhat at least glad he's dead at the end, it seems that although Fred (and his manifestation/alter ego Pete) is far from innocent, we are not meant to completely despise him and wish the worst for him including that death sentence, however much we still want him to suffer or at least be punished for his wife's murder.

In many scenes, he comes across as frightened, confused and sympathetic even, and in certain scenes, either a victim or a hero. Even with knowing that maybe his consciousness is eating away at him as he awaits his sentence, the film let's us into his suffering even when he imagines himself to be the mechanic Pete and its like maybe he was made to do it or possessed or maybe he is guilty but he expresses great sorrow and regret, so he is not all "villain-like-bad" and we can still get behind him and see his humanity.

What did you think, thanks.
