<p>Prompt: Is knowledge a burden rather than a benefit?</p>

<p>Knowledge is a double edge-sword. When used correctly, it can save many lives. Advance in pharmacy for example, has cured thousands of fatal illnesses in the world. However, misused, knowledge is a dangerous weapon. It can become a moral burden to whoever acquires it.
“Batman: the dark knight” has taught me this important lesson. When Gotham city was plagued by criminalism and corruption, Harvey Dent, a virtuous and charismatic attorney stood up against injustice. With the help of Batman, he prosecuted 400 criminals and put them behind bars. However, after his girlfriend was killed, Harvey became a cold blood murderer, known as ‘Two-face’. If Gotham had known the truth about Two-face, hundreds of criminals would run amok; the city would have been covered in flame and blood. Batman made the right choice: he concealed the truth to protect Gotham. Batman took all of Two-face’ crimes and was hated by the Gotham people. Therefore, for the sake of other, sometimes, we must go against our morals. We must lie and deceive.
Not only in fiction, but also in reality, knowledge can lead to despair and sorrow. Alfred Nobel was an ambitious scientist. When he first discovered gunpowder and its explosive power, he sold it to many miners, thinking that it would aid exploitation of natural resources. However, after a few years, guns, bullets and bombs – the beginning of modern warfare were created against Nobel’s will. Gunpowder reeked across every battlefield. Accidentally, Alfred has killed millions. Finally realized the destructive power of gunpowder, Nobel lived in guilt and regret. He wished gunpowder was never discovered. As compensation, Nobel entrusted his fortune to the science society. The Nobel Prize was born, as a reminder to all scientists to never repeat his mistake. From Nobel’s example, the world learned to fear as much as appreciate science.
Is knowledge a burden? Yes it is. It is just as destructive as it is constructive. It can turn your morality upside down, but most importantly, it can be used to hurt others.</p>

<p>I’d probably give it about a 2 or 3. There are several grammatical errors, but that can improve over time.</p>

<p>Instead, I would focus on making the essay more clear. Your second sentence doesn’t really make much sense to me because it is going against what you are trying to prove. Also, your examples don’t really make any sense in relation to the question - in fact your Nobel one goes against your opinion. If Nobel had known what would have happened, he wouldn’t have given it to miners and guns wouldn’t have been created (by him, at least).</p>
