The Dragonborn can be whoever he or she wants. He can side with the Dark Brotherhood and kill Cicero or he could spare his life and destroy them. He could kill Paarthenax and side with the blades or spare him and side with the Graybeards. He can help Ulfric Stormcloak liberate Skyrim from imperial opression or assist the empire and the Thalmor in re enslaving the Nordic people. Practically the only thing he almost certanly does is destroy Alduin, unless you count the DLCs. Talos was never played as in any of the games. In cannon, he conquored all of Tamriel and became emporor, without the consent or choise of the player. He is bound to the limits of the universe and has faded into history while the Dragonborn and other players are free to live another life and another world.

Also, i do not believe that the last dragonborn is a Shezzarine. I don't even think that Talos was. The mer probably just say that to associate Talos with evil (since they hate Lorkhan, weather or not they are right depends on who you ask). Anyways, Lorkhan is destroyed and probably will never fully reform.
