Tragedy is a play that depicts unavoidable consequences of human actions, where mistakes are never forgiven. A tragic hero is the protagonist of high social status who faces severe consequences due to bad decisions or crimes. Theme is the underlying message or life lesson conveyed by the author, usually about human nature or society, that is implied rather than directly stated. In Sonnet 130, Shakespeare conveys the theme that true love is not based on physical appearance or beauty but on deeper emotional connection.
