First of all, let me point out that D&D was historically made based on alignment. Goblins bad. Elves good.

Secondly, I think Larian has done a pretty good job at sticking with a blend of the old but also letting you know that just because someone is of a "bad" race, they aren't necessarily bad. Here are just a few examples:

Omeluum the mind flayer

Blurg the hobgoblin

Some of the duergar like Kith the mason and his apprentice

If you side with Minthara, you discover she may have another side to her that maybe isn't so terrible

The Iron hand gnomes are actually almost like terrorists once you learn more about them. They're not exactly good.
