There’s an element to the season 3 finale of [[True Blood (TV Series)|True Blood]] that some people seem to need explained. While Eric (Alexander Skarsgard) and Russell Edgington (Denis O’Hare) are lying outside Fangtasia in the sunlight, Eric’s maker Godric appears to him and urges him to show Russell some mercy.
OK, aside from Godric reappearing as a ghost – he already met the True Death, after all – the big question is why did Eric ignore his pleading?
Simple. It was vengeance. Godric told Eric that everyone deserved peace and that everyone found peace in death, even a monster like Russell Edgington. Since Eric wanted revenge for the slaughter of his Viking family, simply allowing Russell to die wasn’t enough. That’s why he chose to encase him in concrete – an undefined amount of time trapped in concrete. If he was in there long enough, Edgington would not only have to suffer the grief of Talbot’s death, but he’d slowly go mad.
Or, as Bill said, madder than he already was.
So, the purpose of Godric was to show Eric that there was a possibility to be compassionate. But this actually spurred Eric in the opposite direction, because all he wanted was revenge for his family.
