Who's to say he is a true Sith, eh? If there is one lesson Kira taught him (other than about you-know-what) that would be how nobody is 100% evil. Even if they are 0.000000000000000000001% good, there is some good in everyone. He uses the Dark Side, but he always has a bit of the Light. I can name all beings who truly were 100% Dark Side on one hand. All others still had an iota of Light.

The Son (duh)

Sidious- in fact, his presence, unlike other Sith, is described as feeling not like a fog or a shadow in the Force, but simply like a black void.

Vitiate

Abeloth- well, probably.
