In the new season of Game of Thrones we see the former slave Mossador being executed. Before he dies he pleads for his life. Is this inconsistent with the people of the free cities' behaviour? So as we all know, the "motto" of the people of the free cities is "Valar Morghulis" which is high Valyrian (I think) for "all men must die". When Danaerys asks Missandei if she fears death she simply answers, "Valar morghulis". The people of Yunkai especially seem to widely accept the fact that they will die and try to enjoy themselves as much as possible without thinking of consequence, Daario Naharas being a good example.
So with all that information wouldn't that mean that by that time, Mossador would have accepted his fate and faced it with dignity like every other person from the free cities does?
