I have a pet hypothesis about this. You might be aware of how, throughout some parts of history, particularly post-1500, a lot of people basically tried to make themselves to appear as white as they can to gain credibility from rich, white people from foreign nations so they can also join the club and gain money, power, and esteem?
Well, Far Cry 2 as somewhat aware of race, and Far Cry 3 was supposedly a parody involving race that just played out quite poorly, so I think that they might be going for this idea with this new villain. Notice how he's surrounded by lower-quality military weapons, and trying to emulate the appearance of a European with money with an outfit that makes him really stand out as compared to most anything else you'd see anybody wear in Nepal.
