there's always the Song of Ice and Fire series by George RR Martin. theres nobody good in these books lol. chaotic neutral at best.
more along the lines of anti-hero than pure evil theres-
Among Thieves by Douglas Hulick:
"Rothe has been a member of the Kin for years, rubbing elbows with thieves and murderers in the employ of a crime lord while smuggling relics on the side. But when an ancient book falls into his hands, Drothe finds himself in possession of a relic capable of bringing down emperors-a relic everyone in the underworld would kill to obtain."
Den of Thieves by David Chandler:
"Born and raised in the squalid depths of the Free City of Ness, Malden became a thief by necessity. Now he must pay a fortune to join the criminal operation of Cutbill, lord of the underworld—and one does not refuse the master . . . and live.
The coronet of the Burgrave would fulfill Malden’s obligations, though it is guarded by hungry demons that would tear the soul from any interloper. But the desperate endeavor leads to a more terrible destiny, as Malden, an outlaw knight, and an ensorcelled lady must face the most terrifying evil in the land."
it does surprise me that in all of fiction there isn't a story about an evil guy slaying heroes on his quest to rule the land with an iron fist. it seems like such a simple premise.
