The man Dean sees in the mirror look to be the same one who is later shown lying on a floor dead. Since Dean beat up Cas, he probably has flashbacks of the people he has hurt.
The man was probably a bad guy but still human. So Dean fed the mark.
Looks to be the same guy. The vamp that was shown I would guess is the headless dude on the left, but the other guy still has his noggin, so he wasn't a vamp.
However, if Deans having conscience flashes like that of Cas and this dude, chances are he was a good guy. With it being a vamps place and a girl tied to the bed, maybe this guy was a hunter trying to help her, but Dean killed him anyway?
If he was a bad guy, not even pre-MoC Dean would care enough for it to weigh on his conscience.

Good point! Dean might have been so intent on hunting/killing that he mistakenly thought that the man was a monster. Dean charges in so maybe the man thought that Dean was a bad guy, reacted accordingly but Dean killed him easily. Under normal circumstances, Dean would have made sure that he was reading the situation correctly before killing the man.
Those two bodies lying on the floor are dressed very similarly, that might have factored into both of them ending up dead because of Dean.
But I'm not sure the show would be bold enough to have Dean kill an innocent even "accidentally". So maybe the man was a human and he had been put in charge of making sure that the girl wouldn't be able to escape so he was a victim but tainted like the youngest member of the Styne family was.
Did not Dean just kill an innocent in Cy Styne....
I'm talking more about the audience's perception. I think that the boy qualifies as someone Dean would not have killed if he had not been influenced by the mark but I don't think that Dean killed a complete innocent. The boy had gone along with the atrocities his family was committing. It's very understandable why he took the path of least resistance. He was a victim too. But the audience can get over Dean killing the boy quite easily because he was shown to have taken part in what the other Stynes were doing to a certain degree. A truly shocking bold move would have been Dean killing a boy who had done nothing more than been born into the wrong family. Although it should be noted that Dean might have done just that since it did not seem like he had or needed much evidence against the boy. He just said, "Oh, you are like them. There's bad in you. It's in your blood. Now, you can deny it, and you can run from it all you want, but that bad... will always win."
