Like in pushing dasies, he kills someone to get his girlfriend back to life, but that guy just happened to be a greedy person who robbed people at their deathbeds so, you know, no worries.
Yeah. As someone who's seen both shows I can honestly say that when they did it in Pushing up daisies, it didn't feel 'right' or even as just as it does in Dexter. That bothered me with Pushing Dasies because the girl is particularly annoying and actually makes the show unenjoyable.
