Morality systems are garbage by default, you cannot put morality into numbers. I love the fact that BG3 ignores the alignment chart which is something a lot of DND players do anywhere
Morality systems provide interesting opportunities tho.
Morality systems are a guide line but how my character acts is more interesting imo. I like the idea of Softer systems that can have consequences.
for example i have 2 LN characters in my current campaigns (one pathfinder, one 5e mini campaign as a break from the big one) They have huge diffrences in characters and how they would act in a situation based on how their past and how it informs their actions. One of them had to undergo and alignment shift due to an action that still made sense taken by her being LN but was an evil act. because of it i had to deal with the consequences of loosing some powers until i realigned due to betraying a "natural order" (shes a druid)
To me this what alignment should do and it seems like it might be the case in this. Swen talked about how if you are doing actions that anger your companions they may leave, i hope it goes further and you can loose powers and everything but we will see and ill sure be advocating for that over just a strict alighnment system
