The only thing restricting a wizard from becoming a Death Eater would be if he or she was a Blood Traitor or a Muggle-born.

Why did Snape kill Dumbledore?

Snape had to kill Dumbledore. Firstly, because it was an act of mercy for Dumbledore, as he was already dying, first from the curse he received when he put on the Gaunt ring, and second when he drank the potion from the cave with the locket horcrux. Thats what Dumbledore means when he says Severus.
