In order to get into Heaven you'll have to promise to get along with everyone you despised in your earthly existence.

Those things won't matter anymore.

If there is a heaven as described in most books generally considered "Holy", I doubt I'd have any problem with that.

No prob - it take a lot to get me worked up in the first place - I imagine in Heaven, I'll be even more mellow...

A celestial North Korea for an eternity is not heaven for me.

Pass

I have this ability to shut off to people I dislike. I will be civilised but they will know I have no care for them.

One of the reasons why I'm probably going to hell.

Easy, I've never despised anyone 🙂

As an Atheist I do not recognize any such dimension.
