is everyone perspective important

i believe that not everybody should have a perspective. One reason i believe this is for example someone murders someone else for no reason. So they shouldn't have a say. A second reason i believe this is in a news story might support a particular group of people and it'll seem like more people agree with one group.

For example, in Myanmar Rohinja are persecutedand the UN are respondng. This shows that every perspective is not important because in school the guy from UN was portugese, what does he have to do with this?
