The artist could not, however, portray life just as they saw it because anything that reflected poorly on Communism had to be omitted. People who could not be shown as either wholly good or wholly evil could not be used as characters. This was reflective of the Soviet idea that morality is simple: things are either right or wrong. This view on morality called for idealism over realism. Art was filled with health and happiness: paintings showed busy industrial and agricultural scenes; sculptures depicted workers, sentries, and schoolchildren.
