I have zero sympathy for him as a man. He ruined people's lives who were his friends, colleagues, business partners, teammates, etc.
I have a lot of admiration for his ability on a bike but without the doping he wouldn't have achieved quite as much against the competition he had in the day. I respect him for his crusade against cancer and Live Strong but ultimately he betrayed that organization and all the people that worked there.
Read Tyler Hamilton's book The Secret Race. Good read and gives you a better perspective inside Lance's circle.
In the end, he got what he deserved and paid a heavy price. However, I really don't think he is truly sorry for what he did to people. I think that's just Lance being Lance. He's not a nice person and what he did was criminal.
