I don't know many benefits, but usually this question is based on opinions.
Censoring a publication, film or play involves removing parts or banning the entire production from distribution or viewing. Censorship was put up to keep people from being exposed to offensive, or inappropriate instances, lyrics and images in the media and press. It mainly shields the children from topics that they may eventually encounter later on in their lives. News reports can also withhold or censor their reports to protect victims or innocent parties.
Censorship can also be used by a government to prevent information from being passed on to its citizens. In the past many books and plays have been censored because their content was considered lewd or subversive. Some of these are now accepted by main stream audiences and readers as acceptable.
