A while back, I mentioned how the first thing you should do in Wrath is play through the Death Knight opening. A number of paladins mentioned in the comments that they felt uncomfortable playing as the bad guy, or doing some of the evil things the death knight chain requires, such as torturing people, or killing civilians.
I understand that point of view, and luckily, Invisusira has has made a movie of the Death Knight ending sequence.
It's a must-watch for any paladins who are not going to play the Death Knight. It's pretty much the same as the finale event, only edited slightly and with added music (the music actually adds a great deal to the video).
It goes without saying that this is full of spoilers.
