Fatal Suicide Note

"Silence! Everyone stand up!"
"The suspect Mads is the main culprit of the serial murder case, and his nature is terrible. This court sentences the suspect Wu Jian to death!" The presiding judge slammed the gavel. Beads of sweat flowed down my head, and I felt dizzy and then fell on the chair behind me. If you were there, you would have seen how pale my face was. Seeing this, you must think that I am the serial murderer Mads. But you are wrong. I am not Mads who is about to be sentenced to death, but the defense lawyer next to him.
My name is Kellgaard, and I am an intern lawyer. Now in this solemn court, I can no longer remain calm. Yes, today, I am here as Mads defense lawyer. I understand that even though I have experienced countless mock trials, today, my first official court appearance ended with such a result. This not only represents the failure of my career, but also makes me a morally corrupt scum in the mouths of others, because today, I am defending the innocence of a serial killer. The endless scolding from the audience was like many needles piercing my heart. I collapsed in my chair, almost unable to breathe.
"Mads is a morally corrupt scum. The law will catch up with him. He deserves what he has done. As for the lawyer, he is in cahoots with Mads. He is not a good guy at first glance. He should also be arrested and shot."
A middle-aged man in the audience rushed up and was about to punch me. Fortunately, the bailiff stopped him in time, so I was spared.
