There are rights and there must also be violations to those rights. If you are a student of any humanity subject, learning and knowing what are the essential nature of human rights, and of course, their violations, can be crucial to your knowledge.
Since human, by her or himself, is a very complex creature, it is only natural to expect that any study about the rights, not to mention the abuses, will become less simple. It is therefore, very much useful to have different or alternate point of views to look even at one single phenomenon.
That said, one simple case of human rights violations will yield to different results if it is viewed from different perspective. A land feud, for instance, between people and government can indeed point to different end according to which party’s interest you are scrutinizing. To say that the government is cruel or it is the people that are unlawful might both be true. Both parties are, basically, human. And thus, each of them has their own interest. The question is, of course, to decide a standard that could justify why one interest is better than the other? And that could be a very hard standard to establish even over trivial cases.
