To truly fathom it, read the man who experienced it by defending Armstrong all along:
When he says he’s sorry now, how do we know he’s not still lying? How do we know it’s not just another great performance by the all-time leader in them?
And I guess I should let it go, but I keep thinking how hard he used me. Made me look like a sap. Made me carry his dirty water and I didn’t even know it.
He shouldn’t let it go. The human world cannot function if it is built on bullshit.
