FWIW, I don't think Vic is going to die at the end of the show. I have a feeling he'll end up crippled, unable to do his job or protect his family. I can picture his wife leaving him and him having to move into some crappy crack neighborhood with the show's final moment being some bangers knocking his door down while he sits in a wheelchair with a 12 gauge.
It's not enough for him to die. He needs to suffer to atone for all the suffering he has brought to those around him. I think putting Vic in a wheelchair would bring him a level of suffering he has never dealt with before. In fact, has he ever been hurt really badly on the show physically? I know he got shot once but I can't remember him being out of comission due to injury.
Acevada told Kavanaugh that Vic makes his own fate. I think if Vic was disabled, he'd lose his ability to do that and that would be a much worse punishment for him than death.
What do you see happening to Shane?
