The fact is you should be able to play a good vampire and a evil dawnguard

You can't really say you play as good or evil. I like to think I make the good moral choices, which may include killing a few bandits or vampires along the way.

yeah there going to Reveal 100% of the dawnguard story line...I'm pretty sure there's going to be side Quest for each faction after the MQ

I have two characters specifically so I can play as both. My approach to them is more of selfish and self-less than good and evil. My 'good' character does things to help other people, and my 'evil' character does things to help himsellf. I have to say though, I'm more interested to play as the self-less character and the Dawnguard, I've never been a big fan of playing as a vampire, I always try it and end up looking for a cure almost straight away, but I'm hoping with the changes in the DLC I might feel differently about them afterwards...

There might. But the point is, vampires want to save their race.

I think you can because I consider my character Evil as I do Evil things like steal,murder and wipe out towns like Falkreath ..but that just my opaion

Yea and I never said they were Evil if you look at the forum title it say Dawnguard Dlc : "will you choose to be good or evil" I never said who was good and who was evil

Now we're talking

I actually Love vampiresI think there's nothing wrong with doing what best to protect your people

I'm probably going to be a Good Vampire (as always). Although, I'll end up killing someone eventually... Expecially that Redguard (I think he's one of them anyways) who believes he owns the place.

Dawnguard! Be good and kill all dem vamps. Then I'll join the vamps on the next playthrough and plunge the world into darkness . I like doing both good and evil.
