There is no justice when people break the law which is made evident by the people's need for a court system.
This sentence makes no sense to me.
Currently in Darfur, Sudan, there is a massacre taking place. The government chooses not to follow laws set forth by the UN because of its desire for more power.
But, should citizens of Darfur follow laws set by that government? What if that government passed laws mandating exile for all people of a particular ethnicity. Should the people of that ethnicity just go?
Its crime rate is a fraction of what it is in the rest of the first world indicating that the degree of justice there is relatively high.
Not necessarily. It all depends on how you define "justice." Under totalitarian regimes where lots of people are locked up unjustly, the level of street crime tends to be very low. Does the low crime rate really say anything at all about the level of justice?
My point here is that your argument is very simplistic. It does not take complexities into account. The GRE is looking for more complex thinking.
