Yesterday I took the life of someone who I was close to.
Was he ok with it?
Well, he wanted it to happen, until the last moment when he changed his mind.
It is a crime to hurt or kill someone. You should turn yourself in so you don't have to live with the fear of being found out.
I don't want to turn myself in. Why should I? This guy deserved to die.
You have a very caustic attitude to life and killing your friend was a very violent and harmful act. It was not a good idea for you to get involved in his death and not you must tell the police what happened and take the consequences.
