Much like Tony Soprano after he killed Christopher, Nucky's stock went down in my book when I realized how he gave up Gillian (to the Colonel) when they were young.
Yup.
Here's some irony: On the Sopranos (which Terrance Winter worked on),Steve Buscemi's character was killed by a shotgun blast to the face. In Boardwalk Empire, the last shot (to the face) is the one that kills him.
In both shows he dies on wood. (Sopranos-firewood pile,Boardwalk Empire-the actual boardwalk.)
