Recently WotC made the big decision to rid the game of alignment. And to some that was a sacred cow that just couldn't be slaughtered. I'm of a different opinion. Good riddance.
Objective concrete Alignment is based on an adolescent understanding of how morality works. At best. It's intended for fairy tales. Little kids are the ones who think all knights are shining and that entire races of sentient creatures are simply "evil".
Getting that out of D&D, or simply pushing the idea that maybe it's for new players and not mature ones, is important. Alignment made murder an amoral act in D&D. That's bad because, follow me here, murder isn't an amoral act.
So the big question is: Why do you need alignment in D&D? The answer comes in many flavors, each more wrong than the last:
Without alignment, that means no race is EVIL? They're all just misunderstood! Funny, life doesn't have alignments and there's plenty if evil fuckers out there. Let that sink in for a second. Feel stupid? You should.
But Muh paladins are good! Your paladins were evil to someone. You just don't realize it because you have a narrow view of how morality works. You're a child. Grow up.
But now I can't kill goblins indiscriminately! Sure you can, just as you could before. You just aren't handed a universally justified reason. If you don't have a good reason it might be because your character is a trash person. If they do have a good reason maybe they're not. Taking away alignment allows for nuance. It's a net positive.
So, stop letting the fact WotC did something be the reason you hate it. I don't like WotC and don't hand them money if I can help it, but this is a step toward making the game more interesting and therefore better.
