I decided to rewrite the essay regarding to the prompt about individual responsibility.

Essay

Have you ever ignored someone who needed help and felt guilty afterward? This exercp talks about a man who ignored the dog like everybody else, for he assumed that it was not injured. He later found out that the dog was injured and that someone took it to the vet. This one person made a difference--he stepped out into the spotlight and saved the dog. Everyone is responsible for other individuals because it can definitely save a life.

Clearly, the man is irresponsible. He could have checked the dog and see if it is all right. Instead, he made an assumption like everybody else did. He conformed to them. At that time, everyone had responsibility, but they all became irresponsible to go with the flow. Luckily, the dog was rescued, but the man felt guily for not rescueing it at first. It was possible that the dog could have died. Irresponsibility can result in an individual's death.

On a related note, I was irresponsible during recess. A disabled kid was playing basketball, and the ball rolled off in the opposite direction. I could have picked it up and handed to him, but instead I kicked it far way from him. The disabled kid had a leg problem, so walking was quite difficult for him. What made it worse was that at that time the playground was chaotic,and it might have been possible that some kid run into him and cause him to fall. Shockingly, it did happen. Like the man in the excerpt, I felt guilty. My irresponsibility had an effect on the individual--he fell and was injured.

Everyone is responsible for other individuals, for it is the matter of life. Helping others when they need help impede from feeling guilty later on. There is only one opportunity to help one individual, so make one count so as not to regret.

Better! Could be a low 4.

I'd find better words to replace these:
excerpt (whether it's spelled correctly or not)
impede
regret (which needs a direct object after it)

The verb tense and word choice in this sentence needs fixing. It's an example of non-standard English use that'll stick in a reader's mind as a negative.
He could have checked the dog and see if it is...

These are incorrectly used dashes; you have created run-ons here:
...difference--he...
...on the individual--he fell and was injured.


At first you write that it might have happened, and then you write that it did happen. This is a classic example of wordiness. Get rid of the "might have" and put the two sentences together:
...and it might have been possible that some kid run into him and cause him to fall. Shockingly, it did happen.
