Was this man, confessed mass-murderer, Anders Behring Breivik driven by coldblooded violence - or mental illness?<br/> <br />That's the question facing Norwegian judges on the last day of Breivik's trial for the killing of 77 people last July.<br/> <br />Prosecutors yesterday argued that, while the 33-year-old's acts were premeditated, there was enough doubt over his sanity to commit him to a mental instutution.<br/> <br />But Breivik, who has always admitted his guilt, has said calling him insane is an insult.<br/> <br />His defence argued on Friday that he had a fundamental human right to take responsibility for his actions.<br/> <br />Defence lawyer Geir Lippestad said Breivik had been driven by an extreme radical belief and attitude, which had to be understood 'within the context of right-wing extremism and culture'.<br/> <br />If Breivik is deemed sane, he faces a 21-year jail sentence which could be extended indefinitely.<br/> <br />A ruling by the two professional and three lay judges is not expected before August 24.<br/> <br />Sunita Rappai, Reuters
