But Judge Harry Leinenweber said he was baffled at the descriptions put forward by his family of Rana as a kind, caring person, saying it was so "contrary" to the person who aided the plot on the Danish newspaper's office.
"On the one hand we have a very intelligent person who is capable of providing assistance to many people," the judge said just before announcing sentence.
"But what is difficult to understand is: a person with that intelligence and that background and history of helping others ... how that type of person could get sucked into a dastardly plot that was proposed."
In new evidence submitted before the hearing, prosecutors sought to undercut the depiction of Rana as a dupe by presenting a telephone intercept of Rana's wife, saying that her husband and Headley were just alike and were both immersed in Islamic extremism.
Headley, son of a Pakistani father and an American mother, who changed his given name of Dawood Gilani to scout targets in Mumbai without arousing suspicion, pleaded guilty in both the Mumbai and Danish terrorism plots, and was the star prosecution witness at Rana's trial.
