A rapist is a person who commits the crime of rape, which involves forcing another person to have sexual intercourse without their consent. This can include physical force or threats, as well as taking advantage of someone who is unable to give consent due to being drunk, drugged, or unconscious. Rapists may also be motivated by a desire for power and control over others, rather than simply a sexual urge. The act of rape is considered a serious crime in most societies, with legal consequences for those who are found guilty.
