OK, I admit that the Pathfinder games are relatively good regarding alignment.
I do not remember kingmaker so well, but right now I play the wotr alpha. There I can move towards chaotic evil without randomly killing people. Chaotic can mean you want to have some fun, even during a demon invasion, and it means you disagree with overzealous crusadors. Evil can mean to be pragmatic and not trying to be nice to everyone.
There was one moment where you could deal with some cultists by pretending to be their boss and convince them to kill each other.
Killing people when you can lets you move towards CE much faster though.
I do not think that BG2 was a good example for alignment.
The companions had a strong personality, but you can do this without alignment as well.
Alignment only influences your starting reputation, if you can equip some items and how you react to some spells.
The choices in the game only influence your reputation and the good option usually gives the better rewards. The game wants you to be a hero.
I was playing with an evil assassin only because I could use some items good for backstabbing. I acted always in a heroic way and took the good options and nobody cared about my alignment.
I think PST was the first game where your choices can change your alignment. The alignment tag is not shown in dialogue, but the game informs you when your alignment changes.
