That's a bit over the top. Was the same level of description applied to more typical combat scenes? Some DMs run that way - I had one once who liked to narrate every combat hit in sometimes-gory detail...which was fine for a while but eventually became tiresome when he ran out of new ideas on how to narrate inujries and wounds....
Where The Sopranos is one I've been meaning to take a look at for some time now (I don't have HBO either but I think it's out on hard copy, and believe it or not there's a video rental place three blocks from my home).
Murder an otherwise innocent dragon in its sleep to get a whole lot of gems and gold? Yep.
I'm not a fan of the seven deadlies as moral definers either, I just threw the example in here to give a different perspective.
I don't want 'em to be saints either and, honestly, I'd get real bored real fast if they were. If they want to be evil and steal from the peasants (or each other, it's allowed) or slit the throats of captured prisoners*, who am I to stop them in the meta-game? In-game, sure, there could easily be consequences - including an alignment audit - but in-game is where the consequences should ideally stay (note that I view alignment as an in-game thing).
* - or sell them into slavery, as did a party I once ran...
@Lorithen might remember that one.
