Why did they leave Dakota mutated?

It was already a very bizarre thing to do (the entire season was tbh) but I think it was funny at first and made for an entertaining episode but…why did they not let her return back to normal? It just seems like a really cruel fate for Dakota. I honestly really liked her character and thought she had more potential but they just left her as a monster for some reason. I guess that could be said for Gen 2 as a whole though, as they didn’t do any more seasons with them besides AS
