This fire occurred in a country that will be hosting the Olympics in 2016. I suspect all the major venues and host hotels will be constructed to some US or EU standards of construction that will mandate adequate egress designs, interior finish and the appropriate degree of active and passive fire protection. So if you can afford to go to the Olympics, you'll stay in a fire safe community. The little neighborhood dance clubs will also have a stream of business as the Brazilians will be flocking to Rio and probably only be able to afford being packed into a bar with a single means of egress that will offer a cover charge, making the security strict. The little bar will probably have EPS foam attached to the walls and ceiling because bars are noisy and the owner doesn't want to wake the neighbors. You can hypothesize this scenario is not going to be good in an unsprinklered bar in a slum.
Speaking of Brazilian slums, I've attached a paper that was published in the Journal of Fire Protection Engineering last year on fire risk assessments of slums in Brazil. Based on the data in Table 1, the death of a hundred people in a slum fire appears to be fairly common. So while 200 deaths in a nightclub is sad, it appears that the socity tolerates these consequences for the residents in these areas.
