Souls?

[dahrling]

That slight chance of heaven is offset by the near certainty of an endless eternal and infinite torment of your butthole by horrific demons that shove their red hot barbed wire wrapped fists deep into your sensitive viscera, while gigantic and disgusting spiders eat your tongue out of your mouth while you are screaming endlessly.

That definitely does not describe an afterlife that I want to go to.  And that right there is a 50% side effect of contracting a soul.

No thanks.

But how can souls burn? Aren't souls supposed to be immaterial? 
These are the kinds of question that made me doubt the existence of heaven/hell in the first place.

In the book of Revelations, Heaven (a.k.a New Jerusalem) is described as a very physical place and that always bothered me 
It describes streets of gold and walls made of precious stones. It also describes twelve gates that are always open.

But why would there be walls if there is nothing to protect (what else can we assume if the gates are always open)? They seem to be pointless and how can a flawless perfect god create something imperfect?
