I don't think Armstrong hates Ullrich. First, in Lance's parting speech at the Tour in 2005, he talked about his respect for the two riders next to him on the podium. Second, Lance invited Ullrich to his final party after the Tour, and they partied together. Ullrich was even invited by Lance to give a speech.
I think Lance has a lot of respect for Jan, and vice versa. They were competitors, but they had respect for each other. Lance even talked about his mistaken conclusions about Jan's motives during the past tours (ie: Jan didn't wait when I fell was replaced with an apology and a statement where he said he believed Jan really did wait).
