Do architects have a responsibility to our society, or should they be able to design whatever they want?”

Obviously, architects must design buildings that are safe for people to live in, but what about size, shape, appearance, and materials? Artists can make their paintings and sculptures in any shape and color as they please. Should architects do the same with their buildings?  

What can happen if an artist makes a really ugly painting? What happens if an architect makes a really ugly building?

Did the modern architecture of the 20th century affect society in a bad way? At the time, everyone agreed that modern design would solve most of society’s problems, like crime and hunger. Did modern architecture help these social problems or did the modern movement make things worse?
