He may be seeking justice/revenge for what the Jedi did to the Sith in the past (as what Maul said) as well as end their (to the Sith) tyranny.
And as the Jedi seek the annihilation of the Sith, he may well be protecting his kind from total genocide. As well as purge the corruption of the galactic senate.
As like Anakin said, from another's point of view, the jedi are evil.
His methods might be vile (to us). But to the Sith, there may well be some nobility with what he is doing (as it seems like they function within the concept that the ends do justify the means)
That is my take anyway.
Ah but those can be the most dangerous and most evil villains. The ones who've convinced themselves that they're in the right, and that the ends justify the means. Because they have that level of conviction to their evil.
Take ISIS for example who fit that model perfectly, and are considered by many to be the most evil force in our world today.
