murderer sues victim for ice cream truck

I was recently online browsing the internet and I came across an article that blew my mind. It was about a convicted murderer who was suing one of the victims he didn’t manage to kill before he was arrested. The man in prison who had already killed a man on the west coast flew out to New York to meet up with a friend that was selling him an ice cream truck for 18,000 dollars, but took his friend hostage and held him at gunpoint when he didn’t get the ice cream truck he paid for. In the end the man was convicted of his previous murder and made headline news when he agreed to plead guilty if he could have his favorite foods from KFC and some Hagen Daze ice cream. Now he wants revenge he is suing his friend for the full 18,000 dollars from prison and he even wants a refund for the travel expenses he used in flying out to kidnap him, the crazy part is he is winning his case in court! I still am a little unclear as to which side I am on because I don’t know some of the details. But should our judicial system allow this? Should we let convicted murderers sue their hostage victims from prison? At first it might seem a little crazy but after all the man never got his ice cream truck, some people just love ice cream I guess.
