I think the point of Krom's post is that a lot of characters are cliché or off-putting at first blush, but become more realized people given enough time.
But if all the characters are the same basic story (comes across as evil at first, but turns out to be something else later on), then how is that in any way meaningful?
Seems to me that Larian has, from a writing standpoint, created effectively just one basic character, and then slapped on different outer shells on that one basic character to generate multiple characters. That is my point.
Your gross generalization proves you at best don't care about BG3 plot. I agree with Krom post earlier, It seems you have missed or ignored every nuances which makes those characters unique and interesting.
