Answer:
Hamlet was also basically forced into the duel in which he kills both Claudius and Leartes.
Step-by-step explanation:
William Shakespeare's "Hamlet" revolves around the story of a young prince Hamlet who wanted to avenge the murder of his father, King Hamlet. And in that process of trying to get revenge, he brought about the death of not only his enemies but also his own.
In Act V scene ii, we see Osric telling Hamlet and Horatio about the 'bet' that King Claudius had made about a duel between Laertes and Hamlet. Claudius has bet "six Barbary horses . . . six French rapiers and poniards with their assigns—as girdle, hangers, and so." This was to be given to any winner of the dozen rounds of which Claudius believes Laertes needed just three hits to defeat Hamlet.
And in that duel, Hamlet not only killed Laertes (with his own poisoned sword) but also Claudius by stabbing him with a dagger.
