It's the Ying-Yang balance of life, a common theme in revealed religions.
Now, about Pelosi and Sebelius ~ Pelosi has an excuse. Sebelius does not.
Nancy's father was what is known as a "siciliano protectore" ~ a thug who protected the interests of organized crime. I am sure as mayor of Baltimore he taught Nancy how it's really done ~ and she never realized there's a big difference between right and wrong. Subsequent education at a Catholic women's college would hardly be able to dent that problem.
Now Sebelius ~ she invented her evil on her own ~ her education was just something to sough off like old skin.
Then, too, there's a good possibility that Sebelius would have been diagnosed in an earlier time as "possessed". Nancy simply uses so much botox she can no longer sense anger. Seems you need something other than a numb space between your eyes to do that!
It's probably already too late for Kathleen to come up with a deathbed conversion, but Nancy can pay penance by coming across with evidence of Democrat crimes sufficient to put half of Capitol Hill in prison ~ anything less than that and I'm afraid she's as doomed as Kathleen.
On deathbed conversions, see tagline quote by Flannery O’Connor.
