Design is perceived by most as a positive concept meant to improve people lives. But it is first a means to answer efficiently a specific purpose. How can we morally accept that the act of killing led to the development of an important design industry? In past decades Design has emerged as a promising field of study that led to the development of specific training courses but also of cultural institutions entirely dedicated to this domain. However, the concept of Design has to free itself from chronological and moral limitations to fully encompass all creations produced by the Human brain, good or bad.
