Good vs. Evil: Is there really a difference?

Author's Note: I read this quote from Jekyll and Hyde: "There’s a rather singular
resemblance; the two hands are in many points identical: only differently
sloped.” (55) It made me realize that there is very little difference between a good person and an evil one. Good and evil have exceedingly similar qualities. The only difference between good and evil is the perception one has when judging
them.

"Killer!"
The muttered word echoes through the otherwise silent cell. The guards shove the prisoner inside, lock the doors.
"You don't deserve such a light sentence, you murderer."
Thirty-five years.
That was the sentence. Thirty-five years in a prison cell for pushing a man out
a window and down four stories. The time seemed so little, and yet so much.
The prisoner sat hunched over, clutching her knees and hiding her head behind her hair. The silence was oppressive, a more menacing presence than the guards or the other prisoners. A small sob escaped her mouth. Her shoulders shook, and she
succumbed to the tears.

She hadn't meant to kill the man.
He had been standing over Julia - her precious Julia - and she had heard the girl crying. Her daughter didn't cry for much, she knew that. Her daughter was brave. And that man - she didn't know who he was, and no one had the right to be so close to her Julia! She had rushed over, pushed at him, made him back away from the child.
He swore, but she had paid him no attention. Julia was bleeding, and that was of more importance. She lifted the girl gently, prepared to take her home, but the man grabbed her roughly. "Stop it!" she had cried. "Leave us alone!"
"I don't think so," the man had growled. He pulled at Julia, tumbled her from her mother's grasp. The girl screamed.
At the scream, her mother had snapped. Letting out a ferocious cry that only a mother knows, she hit at the man, anger suffusing her body. Her intensity surprised him, and he flinched backwards. His weight hit glass and the crystal shattered. He fell backwards, crying out in fear as he plummeted downwards.
He had been hurting her daughter, but now Julia was safe. That was all that mattered. She hadn't meant to kill him.
