Don Quixote’s bravery get him into trouble, as seen when Don Quixote attacks the sheep and when he is attacked by the Yanguesans. Don Quixote is a brave man, taken up the ideals of chivalry, he goes around righting wrongs that he thinks need righting. To Sancho’s dismay, and both of their health, Don Quixote’s bravery is the catalyst that starts most of their adventures, and causes most of their problems.
Rocinante wandering off to mate with a group of mares, initiates the problem between Don Quixote and the Yanguesans. Instead of grabbing Rocinante and getting out of there, Don Quixote’s bravery further worsens the problem. This causes Don Quixote and Sancho to both get beaten up by the Yanguesans. Don Quixote could have quelled the situation by talking to the Yanguesans, or keeping a better eye on Rocinante in the first place. Instead Don Quixote sees Rocinante being attacked by the Yanguesans and charges into battle even though him and Sancho are heavily outnumbered. This shows Don Quixote’s bravery and even loyalty to Rocinante, his faithful steed.
The murdering of the sheep
When Don Quixote and Sancho are confronted by a massive dust wall, Don Quixote leaps to the conclusion of a battle being fought and without a moment to lose he charges into the fray. Even with Sancho telling Don Quixote that the dust cloud is caused by sheep instead of armies fighting, Don Quixote is not deterred, and only after “dash(ing) into the middle of the squadron of sheep and began to attack them” and later getting some teeth knocked out by shepherds, does Don Quixote realise that they are indeed sheep. Don Quixote’s bravery to rush into battle was what caused him to kill some of the shepherds sheep, and made him lose some of his teeth. Don Quixote’s bravery is shown by him charging into something unknown to him.
Don Quixote’s bravery, while being a key part in upholding his morals, is the cause for many of his problems.
