Spoilers obviously but I really wanted to give it a try but it is such a chore to go through.
Literally nothing incentivizes me to do evil things... well besides doing evil just for being evil. If anything I am penalized for going down that path even though I should probably be incentivized more to be evil rather than good. So if I am good I know that all the tieflings I help will be found in Baldur's Gate so my good actions will have longterm benefit. Apparently if I help Mol I would also have the new thieves' guild as allies? Just so many characters and potential plotlines for Act 2 and 3 that I anticipate in seeing them resolved in the next acts.
There is also the underdark issue where the refugee fungal king wants me to betray my current employer for "rewards"... buddy I am already getting rewards, why should I clear a WHOLE city of friendlies? There are also many unrelated NPCs that will give me quests and show me interesting interactions that I would probably have to kill too. Why? Why should I do that?
It just seems to me the only people that would go down the Evil path are those that are somewhat masochistic and also psychotic. Only the insane would do bad things because it makes them feel good. Larian needs to incentivize me to be evil.
Here are some potential ideas. 1) Give me Sazza as a companion... well more like a subservient underling. I am a True Soul afterall. 2) Give me Minthara as a companion, maybe I can bend her to my allegiance rather than the Absolute's down the road. 3) Give me a Goblin Horn to summon a goblin raiding party to aid me in difficult fights. 4) Give me thralls and minions of true soul. Like the two siblings I meet on the road, they could be interesting characters to learn more about. And who knows maybe to torment or reward as I see fit. 5) Give me the option of not killing the refugees and druids in a massive massacre. Weren't there talk of slave traders in Goblin Fortress? Give me choices! Maybe certain characters can be spared and sold, Why should I kill Mol and her buddies when I can just spare them and have them work for me!
There are a lot of options. Maybe the evil playthrough can impact my camp look as well. It would become more savage looking, maybe I can hire Drow and Ogre merceneries. Have evil pillage and conquest questlines... something! Honestly burning the orphanage just because it makes me so edgy is not that attractive of a choice.
Anyway that's my 2cents. I did not find the evil play through interesting at all.
Doing evil "things" in general is the easier solution. A alignment system would help clear this up so people would actually see what they do is X alignment. I'll do two examples, the first is the confrontation at the ruin entrance. You hear people talking loudly at the entrance, they look like a band of thugs and actually are their to plunder the ruins for richs. Do you leave them be and find another route? Confronting them, you can out right kill them, lie / minipulate, try and convince them, or fail your rolls and go into battle. If you go into battle do you out right kill them or do non-lethal damage and knock them out? I would guess the people that failed the rolls probably 90% of them out right killed them. What alignment would you consider this. I'd say its a evil act, cause you just murdered a bunch of humans cause it was easier than knocking them out.
Example two: there is a goblin in a cage and a Teifling has a bow pointed at her, most of you should know this scenario. Even if it is a goblin do you try and save the creatures life or let her die.
These are alignment based choices, there is no "evil route", there are good, neutral, lawful, chaotic, and evil choices.
I was going to post the alignment section of d&d 5e freebe pdf but that small paragraph doesn't explain anything.
Chaotic evil is an example of it actually often being harder. If a PC wants to play like a "murder-hobo" I wouldn't say that it's easier, when entire world is an enemy. Also having reliable allies, access to merchants, etc; none of this can happen if PC is playing like a "murder-hobo" and just slaughters everyone. Also you lose access to information from NPCs if all that you do is just attacking them outright as soon as you see them (although it's fixed to a certain degree thanks to Speak with Dead spell).
Also being very selfish (and that is described as evil thing pretty often in D&D, even if you cause no harm to others) can cause lots of problems, simply because it can make people turn against you. Or Imagine an evil, 2000 IQ wizard who is ruling an evil kingdom and manipulates the people living there into believing that he is actually good. I wouldn't describe this as a "easy solution" either.
I wouldn't say that it's "easy choices" in general. It's mega dependant on situation. Good that entire alignment system is being slowly made less and less important with each edition, because all that it does is making very limited character creation choices and makes the entire narration too simple. More and more morally grey characters appear in new games because they are the most interesting ones. (and they resemble real life personalities the most)
