Yes this is true but the different is that Cao Cao have the protection of Indra, he was able to be forgiven ( more or less) give his help tto he DXD team in the volume 18 and and the volume 21, now he have a cooperation with the SlashDog team's. Thanatos have more possibilites to get the freedom( he want that Hades don't change the Hell for this he have attacked Koneko and Kuroka). Probably Thanatos could help the DXD to figth the Hades's Legion. About Nyx is very hard but Kuroka have near kill Rias and Koneko but she joined the Issei's harem...
