What would happen if evil triumph over good?

Hi... For me, I think that it will be the citizens who are staying in the nation will suffer and the nation might go extinct because of all the wrongdoings. Also, no people will want to go to the nation where there are so many evils and as a result, the nation economy will also suffer very badly and it will be just a matter of time when the nation will go extinct. Even if the nation never go extinct, the people will all hate each other as they are mostly evil and all of them will only care for themselves and they will all be fighting among each other for their own benefits. The good people will then be bullied by the evil people and they will also soon move out of the nation. Hence, country will be chaotic and messy and the country can never survive. Just my point of view.

We see examples on the news programs every day, of the fighting in the Middle East.

I don't know if nations go extinct because of evil. Very often, nations disappear when they are conquered by other nations. Do the conquering nations constitute evil? cheers!!
