Soul of Negari? Haven't read it all but its good.
Overlord the novels? Really great, with much greater dark fantasy depth than the anime.
There's this popular I Am The Fated Villain. Mc is pure evil schemer sc*m. Not my cup of tea because I dislike both rape and harems but the scheme part is good.
History's strongest senior brother. Not really evil but it was good. Dropped it out of boredom at round 1.3k chapters.
A Black Market Litrpg. Evil fantasy intergalactic mafia boss reincarnated into steampunk magic fantasy. Does typical gangster sh1t. Selling weed, opening wh*r* house, fighting in gang wars, etc.
Custom Made Demon king. MC is a demon in Hell. Multiverse with hell and heaven fighting (n more). Tons of references (like Mc entering worlds of Magic Gathering, or Diablo's, etc...)
Mc got a system and was an artist. Can draw stuff into reality for souls. Tricks pple left n right and become rich ?.
Dont really know or remember other evil novels.
