Godric's Death (Season 2, Episode 9)
Eric had been all badass and no heart, until his maker showed up. Godric was a 2,000-year-old vampire who had spent much of his immortal life hating humans and enacting violence upon them . . . until he experienced a change of heart and sought to repent for his ways by offering himself as a sacrifice to the Fellowship of the Sun. Godric's plan went awry when Eric intervened, but Godric still chose to "meet the sun" with hopes his sacrifice would set an example for peace amongst the species. Despite an intimidating start, Godric's compassion at the end of his life made his death one of the most upsetting moments to date, and his arc on the show was a testament to the range and depth a vampire's life could have. Like Gran for Sookie, Godric would serve as Eric's moral compass in later episodes, both encouraging him not to commit suicide while captured by Russell in Season Three and egging him on to drink Sookie's blood in a dream state in Season Four.
