    6. What's more, some people took a look at this story and thought "Ok, Johnathan is DEFINITELY responsible for this murder. But MAYBE, The Jenny Jones Show might be partially responsible, since THEY'RE the ones who ambushed him with this news that his gay friend had a crush on him."
    Ok, that's not a valid excuse. Correlation is not causation.

    By definition insanity means that one has lost touch with reality. The legal definition of insanity is based on whether or not a person can determine what is right from what is wrong. So a person could be hearing voices telling them to kill someone but still know that these actions are wrong. One can have obsessive murderous thoughts that will not abate until he or she yields to the compulsion to follow through with the action. The individual is still guilty under the law because they know the murder is morally wrong.

    You should see that awful Bianchi agreeing and planning with his own cousin who is probably even worse , and possibly even enjoying this whole gruesome offences to the last step to pose the bodies of their own helpless victims ; only then you'll know how much he's full of it , in my opinion those were two of the worst human beings ever not just as criminals .
