We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Purgatory, it seems, is the place for purging of sin and evil through penitence and painful self-awareness, and embracing virtue. A beautiful seven-story mountain. In some ways, Purgatorio is begging us to take purgatory today rather than later.
Protestants have never liked the idea, but CS Lewis did somewhat reluctantly note that we will all need to be cleaned up before entering heaven, and perhaps it takes a long time rather than a short one. Okay, "time" may be a wrong place to start anyway.

For the rest of us you can try Inferno by Niven and Pournelle.
The idea of Purgatory does not run counter to the notion of already living in an aspect of the Kingdom - a thorny topic few I know agree upon with any humility.
I'm regularly cursed by secular and spiritual alike for simply saying "I don't know".
However, I maintain absolute assurance that everyone I've ever known has been cursed with the human condition of a combination including but not limited to ignorance, stupidity and self-service so the possibility of addressing said condition to the best of my God given ability sooner rather than later is very important for me.
All that being said, some of the most memorable words I've ever heard are "Lighten up Francis".

I like the way you think. It's hard to wrap a human mind around any concept of eternity. Is it a kind of existence where change still happens? Is it a mode that simply reflects where you were pointed at the moment of death? I don't think God encourages us to split hairs about this, or play at dice with it. The last thing we should ever be thinking is "There will be plenty of time to clean that up later." Every choice you make is building who you are.
