Lae and shaodw actually dont disagree all the time, Gale isn't too moved against you, astation is kinda evil anyway.
actually finished the evil route with all of them at least neutral to me or 1 level higher in reputation.
The exp gain for evil is far higher than the good side.
Your companions do disapprove of your action but mostly they will disapprove of how you say things as well. That and Lae pretty much disapproves of everything you do, so dont sweat it.
Chaotic Evil is harder than lawful.
Less traders alive haha.
Your side quest progression is semi stunted if you planned to do things with the druid grove, I'd consider doing the side quests first rather than jump straight into the mess. You can still be evil for side quests, but also keep in mind that a greater deal of xp is earning through killing and not through quests.
