And as Tempest mentioned, Salome believed that the only non-Authority vampire capable of ending Roman was Russell. If Roman was only 500, she could've seduced Eric into doing the deed, rather than going to the trouble of digging up a 3000 year old psychopath who was in every way imaginable more dangerous than Roman, and likely to turn on the Authority at any given moment.
