Alright I'll tone down the sarcasm. In all fairness I should have said "chaotic evil" as that might have given my obviously stupid decisions a bit of context here as most people can probably gather that perma-killing half of your companions just because you can is really bloody stupid.
For the effort that one puts in both ways, the overall gains and losses are not equal.
-(Lawful) Good: Killing the goblins and helping the refugees. You have more companions at your disposal, better loot and more income sources
-(Chaotic) Evil: Helping the goblins and butchering the refugees and druids. You never have to say "I'm sorry" but that's about it.
These examples are pretty heavily based on some very dramatic extremes here, polar opposites.
On the good playthrough I tried for lawful good. I went very much out of my way to be a good guy, reasoning that the goblins would continue killing and butchering if left alive. made a bunch of mistakes and bad rolls but, by the end where the cutscene plays and you get the "thanks for playing" I had a hoard of stuff and at least medium approval with the companions, apart from Shadowheart who hates my guts.
On the Evil playthrough I shot for chaotic evil (In hindsight lawful evil would have saved me a LOT of trouble and very likely would have had less of a lethality rate but, I digress.) I went out of my way to be as wicked and malicious as possible forsaking common sense and sensibility for maximum cruelty to the point of killing scratch This playstyle is pretty severely punished and borderline nonviable as I ended up perma-killing several companions (scrolls don't work, the skeleton won't fix em up they are dead and gone for good and all with no get out of death cards) and vendors where the only worthwhile thing I really got out of it was never having to say "I'm sorry" not even to Zelvor.
