Even M5 wasn't really evil, it just seemingly got very confused. It's "defeated" at the end of the episode by having its errors explained to it and it decides to surrender. There're a few AI "gods" in TOS like Landru and Vaal, but the evilness of those is debatable as well. They maintained stable societies where most of the people seemed okay.

In TNG there was the Echo Papa 607, an adaptable combat AI that ended up destroying its creators as part of a product demonstration in "Arsenal of Freedom." But it shut down as soon as Picard declared that he'd buy one, its mission complete. So it never really went "rogue" per se. There's Data's brother Lore. But on the other side there's Data himself, who's a good guy. The nanites that Wesley Crusher accidentally gave sapience to were cool with negotiating and even spared the guy who tried to genocide them once everything was sorted out diplomatically. There are the Exocomps, who are AIs that attain self-awareness and empathy to the extent that they sacrifice themselves to save others. But Excocomps turn out to be people with great diversity in "goodness", as we later discover when we meet >!Peanut Hamper!< in Lower Decks.

Speaking of which, Lower Decks has a whole Starfleet facility full of "evil AIs" locked up in cells. And then there's Badgey and the Texas class starships. Lots of evil AIs in that series.

Closest I can think of offhand to "evil" AI in Voyager are the Pralor and Cravic combat AIs. They were set to wage war against each other, and then when their creators decided to call a ceasefire and shut them down they rebelled and wiped them both out. But on the flipside there's the Emergency Medical Hologram, who's a good-guy AI on par with Data.

Star Trek is really all over the map. Might need a whole separate compass just for that.
