That was one of a host of things that Armstrong mentioned in the second part of his global exclusive TV interview with Oprah Winfrey.
In the first part, Armstrong admitted for the first time to using performance enhancing drugs and having blood transfusions on his way to winning seven Tour de France titles between 1999-2005.
Previously, Armstrong had vehemently denied use of anything illegal but as evidence grew and witnesses became more willing to speak out, it was impossible to deny any longer.
Late last year, Armstrong was stripped of all his Tour de France title wins and then in the first part of his interview with Winfrey confirmed what most of the world already knew, or at least expected had happened.
In the second instalment, Armstrong revealed an emotional side when recalling the impact his drug-taking actions had on his family, particularly his 13-year-old son who vigorously defended him.
Armstrong did also continue to show his stubborn and defiant side discussing how he felt his ban was too harsh and that he feels he deserves the chance to compete again.
Here are some of his key statements:
"Hell, yes. I'm a competitor. It's what I've done my whole life. I love to train. I love to race. I love to toe the line. Not the Tour de France, but there's a lot of other things I could do."
"I deserve to be punished. I'm not sure that I deserve a death penalty."
"I told Luke (his son), I said, 'Don't defend me anymore. Don't. Some kid says something, do not defend me. Just say, 'Hey, my dad said he was sorry.'"
ON HIS FORMER SELF
"That is a guy who felt invincible... Truly believed he was invincible. That's who that guy was. That guy's still there. I'm not going to lie to you."
"The older kids need to not be living with this issue in their lives. That isn't fair for me to have done to them. And I did it. And also for the little ones who have no idea. They're two and three. They obviously have no idea. But they will learn it. This conversation will live forever."
"I'm the type of person that needs to not do it sporadically. It needs to be consistently. I've had a messy life."
I can look at what I did -- cheating to win bike races, lying about it, bullying people. Of course you're not supposed to do those things. There's another moral to this story. I just think it was about that ride and about losing myself and getting caught up in that and doing all of those things along the way."
"Do I have remorse? Absolutely. Will I continue to? For me, this is just the first steps in. I'm paying the price, but I deserve it."
STEPPING DOWN FROM LIVESTRONG
"It was the best thing for the organisation but it hurt like hell... That was the lowest."
LOSING HIS SPONSORS
"You could look at the day or those two days or the day and a half where people left. That was a $75 million day."
"I am deeply sorry for what I did."
"I also feel humbled. I feel ashamed. Yeah, this is ugly stuff."
