"What you did that you ended in prison."

"I saved him."

"That's not true. Saving someone is not a crime."

"It is a crime in the eyes of justice."

"Will you elaborate it to me?"

"He was my patient. He was dying. His pain was immeasurable. There was no cure. He said he didn't wanted to die that painfully."

"What happened then?"

"I saved him from pain"

"Then why are you here?"

"I killed him."
