Lucius Malfoy: Famous Death Eater and father of Draco Malfoy. We know that Lucius was put in Azkaban after the events that occured in the Ministry of Magic at the end of OotP and that he continued to reside there during HBP according to Dumbledore. My question is why exactly was he not released. It is clear that the dementors are loyal to Voldemort, so why would he not want one of his prized Death Eaters free?
I feel that Voldemort is unhappy with Lucius for his failure. He might be keeping him there to make him suffer. Snape already told us that Voldemort was most likely giving Draco the assignment in order to kill him, in revenge for his father's mistakes. And to kill his only son would ensure the end of the Malfoy family line... a fate that I'm sure Lucius would not be happy about.
Christina was telling me that Draco will most likely be protected by Snape, through whatever protection he can give, allowing Voldemort to take his rage out on Lucius. I think that this is very possible. I think that, although I do not want to believe it, Lucius will be one to die... I think that Draco will have a change of heart and turn to the order when he finds his father dead at the hands of Voldemort.
So I think there is no life after Azkaban for Lucius...
