Did vibranium make Wakandans so barbaric and bloodthirsty?

On my planet the succession to the royal throne is determined by mortal combat. President Ackbar™ and I defeated two other Mon Cals to become President and Vice President respectfully.

The losers were then served as a delicious sushi buffet! Good times.

Well that was dull and repetitive, if you wish to repeat yourself to inflate the size of your post in try finding different ways to say the same thing not just repeat the exact same phrasing every other line.

As for the point of your post or should I say the question posed in the post as we all know the point isn't to actually ask any question more so a ruse to allow you to bitch about something MCU related as it's all you do, but to the question no it's not due to vibranium.

You seem to mistake technological advancement with them evolving beyond their traditions, Wakanda is famously an isolationist culture they only rarely interact with outsiders and only ever to really benefit their own agenda or needs, Wakandan culture is technologically advanced but still deeply rooted in it's past, you add this to the fact that the leader of Wakanda is also typically either the Black Panther or were the Black Panther the nations greatest warrior and proving oneself in combat for the right to lead also makes sense.

If anything the ritual combat of leaders to determine who should lead is far more peaceful, I don't know as I haven't seen the film yet if T'Challa has to fight to be allowed to call himself king or if he is challenged and his ascension to the throne is just a time when any who wish to may challenge more easily, this negates large scale war between tribes limiting the number of deaths to a single person instead of hundreds or thousands which is far more civilised than open warfare, even with Killmongers challenge it makes sense rather than a violent coup where the royal families allies are divided leading to civil war, a member of the family can simply challenge for the right to lead, again limiting the deaths of the Wakandan people.

Considering that Wakanda recognises a monarchy not an elected government violence is the only way to force change in leadership, hell even with elected government's violence is also a tool to force regime changes, the fact Wakanda has a sacred and honoured method in which to allow for the change and yet protect it's people at the same time is far from barbaric, bloodthirsty, primitive or any other crap you want to call it, but we all know you don't care you just want to shit on the film.

Also the whole fight to the death thing also keeps the right to challenge from being meaninglessly used, only those willing to die will challenge, so people wont do it as a lark, it keeps the crown as being something only few who have strong convictions will go for, if theres no risk anyone would challenge, even those who have no business leading.

And who says anyone has to die in the transition of power? Either opponent can submit without forfeiting their life and honor will still be satisfied. OP must have watched a very sketchy bootleg of the film. Doesn’t seem like he followed the details of the plot very well.

Its a great point. The film basically is reinforcing the stereotype that Africans will still be primitive and savages even if they had kept their natural resources.

Its part of their culture, so who cares? In America our presidency is rigged by the rich and powerful so What's to say we are any better?

Actually Hillary lost. Trump was not the establishment candidate or even the Rebulican establishment candidate.

Wakanda is an absolute monarchy and thus a dictatorship.

And how did that work out for the U.S. ultimately?

Contesting a hand to hand combat duel where the loser may be legally murdered to decide the throne which requires attributes greater than just simply skilled combat is pretty primitive. The fact they also heavily believe in panther gods, ancestral rituals and are separated into "tribes" (basically real life Africans) also show even though they may possess advanced technology, they are not yet scientifically cultured as in a secular democratic society.

Whose rights are being violated if both participants are willing and can opt out of the process if they do not wish tp pursue the throne?
