I pushed the old man into the incoming train's path
Why did you push the old man into the incoming train's path?
I wanted to hurt him, why else would I do it?
It's a very sinister act to push people into the path of trains, and if you really did that you should turn your self into the police. If you commit murder, you deserve to be in prison so unless you want to be a fugitive on the run, you should tell the police what you did.
He didn't die and I am not going to do anything about it. I got away with it.
This is still wrong even if he didn't get hurt. I hope you never so this again and understand that even if you don't turn yourself in, you could still face consequences for your actions.
