Do you think a Page of Doom would be liable to badly misinterpret their aspect? Like, in such a way that they managed to convince themselves that the game wanted someone of their aspect to 'bring doom' to other players (As in kill them) or something along those lines.

I mean, I don’t see why not. You could argue they may be Served ‘Doom’ as in, shown the awful things they’ve got to do, convinced to follow that destructive path, and then following it maybe?
