If they will name an android Albert 6, your thoughts will be definitely right. In that case David 8's character connects with king Edward 8.
I have a question: in Prometheus David's full name is David 8? I don't remember any hints for this. I know, in the promotion video they mentioned, it's David 8, I mean the series number. But some people think, David in Prometheus is a special edition for Weyland. Is he David 8 then?
My opinion about this: David is definitely van be an Aryan character, so the connections between him and the nazis is pretty easy if you want to interprete his character in a political point of view. (Actually it's very symbolic in some way, when he cut his hair in AC, hé cuts firstly the blond hairpart). But honestly I'm a bit tired of these kind of political hints. Don't get me wrong, i see the connections and your idea is relevant. But if we want to talk about genocides, there were much more genocides. I don't want to count them now, but I'm sure, you know what I'm talking about. That's why I'm a bit tired of these kind of political correlations ín films.
