The big draw back is the evil party members will leave if your reputation gets too high...as there is no option to explain your motives. To reassure them or explain to them that, "Hey, I'm as evil as they come...patience. We earn that trust. We lull them into security...then, they're ours! We will use that when needed and do what we want to do. We can frame whomever we want! Cast the blame elsewhere! Have them help us conceal/destroy the evidence...then, if they show signs they will be unable to live with the deeds asked of them and expose us...well, we help end their doubt and guilt, by ending them. No loose ends."
Anyhoo lol...I do hope the evil options in BG3 go beyond Stupid Evil.
In BG3, characters can leave because of your decisions, even if your relationship is neutral or not bad with them. Some characters just leave if you don't choose what they wanted. Some characters, such as Gale or Shadow, can be persuaded. I don't know if this will change in the future or if it will be possible to return our companions if they leave.
