They started off as something, and their time expired, for better or worse, as unfair as it was. They entered into a state described by their leader as eternal damnation. They will suffer in the Shadowlands for it.
Your argument is advocating for zombies or undead to have a place in the world among the living, be it intelligent Undead or not. That's macabre. Soul-based constructs exist as they were intended by design. Yes, humans, dwarves, and gnomes are by products of curses and other external forces as well, but those changes didn't make them parasitic. Undeath defiles the very land Undead walk, withering it away. Look at the Plaguelands. It's a burden on the planet and other living organisms.
Even in media when Undead were depicted as somewhat sympathetic like in [film] Warm Bodies, it came with a cure. If Undead just want to exist "because" without contributing anything to the world around them, but in fact defiling it as their very presence does, it then becomes an infestation that can't be justified unless you really just like the playable race.
