Evil content is wildly underwhelming, there are very few evil options in dialogue and if you pick the few that are there, you mostly just get ignored and plot-expositioned anyway, Fallout 4-style.
There are no opportunities to be crafty evil, and no reactivity to be murderous evil, and most major quest rewards depend on you making heroic choices and actions.

The few elements that seem like they should allow some evil play is either bereft of it or really bland.
The only thing Evil characters can do with the Hag is get a really severe debuff (to be fair seems like there was a bug, there may have been a point to doing that but I'm not sure what it's supposed to be for now) and in the Goblin Camp you can basically only make an uninformed and uninspired "Sure I'll go eradicate the Druid grove for absolutely no expressed reason or promise of reward" choice, along with a pretty cartoonish torture scene.

I really wonder why they want us to "play evil" when they basically haven't implemented it
