Final answer:
Shakespeare's plays often take their names from their main characters, as seen in 'Hamlet' and 'Romeo and Juliet', where the titular protagonists' destinies are central to their tragic storylines.
Step-by-step explanation:
There are multiple plays by William Shakespeare that bear the names of their title characters, and often these characters are central to the storylines. In plays like Hamlet and Romeo and Juliet, the protagonists share their names with the titles and their fates are intrinsically linked to the plays' outcomes. In Hamlet, the Prince of Denmark is the protagonist who ultimately seeks revenge against his uncle who has usurped the throne, resulting in a tragic series of events that conclude with Hamlet's own death. Similarly, in Romeo and Juliet, we follow the doomed romantic journey of two young lovers from feuding families in Verona, Italy. The tragic end for these characters is well-known, with Romeo taking his life mistakenly believing Juliet to be dead, and Juliet, upon awakening to find Romeo dead, taking her own life in turn.
