Wikipedia:Criticism

All encyclopedic content on Wikipedia must adhere to neutral point of view (NPOV), which means representing fairly, proportionately, and, as far as possible, without editorial bias, all the significant views that have been published by reliable sources on a topic. If significant views include negative criticism of the article subject published in reliable sources, then they should be incorporated into the article content in an appropriate and neutral way.

In most cases separate sections devoted to criticism, controversies, or the like should be avoided in an article because these sections call undue attention to negative viewpoints. Articles should present the prevailing viewpoints from reliable sources, whether positive or negative. Segregation of text or other content into different subsections, based solely on the apparent POV of the content itself, may result in an unencyclopedic structure, such as a back-and-forth dialogue between proponents and opponents. There is no requirement to include criticism or controversies in an article.

Wikipedia's policy on biographies of living persons requires exercising special care in presenting negative viewpoints about living persons.
