Suffering is meant to teach a lesson. Whether the lesson is meant for an individual, a group, a culture, a nation or a planet depends on the suffering. The nature of suffering is that it shall continue until the lesson is learned.
Words in general and adjectives in particular have power. It is a power that comes in degrees or shadings. People and even societies can make value judgments on others just by the shadings of the words they use. Weird, strange, different and unique are really just different shadings of the same word but evoke completely connotations when applied to individuals or groups of people.
