Souls can remember, talk, reason, ask questions, feel emotion, justice and rest. Presumably they can feel pain as well as comfort.
'Presumably' puts us back in the terrain of uncertainty and interpretation at best. Meaning your guess is as good as mine. I mean to point out the uncertainty of the interpretation versus pointing out who is wrong and who isn't. I think it's a good discussion.
Separating the soul from the body is still not the same as a dead soul. As you quoted, a soul can do a lot of things. However, all the things pointed out in the Revelation scripture you quoted don't require a physical body. God, the angels, demons all can talk , feel emotions, reason and rest despite having no physical body.
What does require a physical body according to the Bible? One example is sex. The angels transformed their non physical bodies into physical ones in order to feel the pleasure that only a physical body could feel. Jesus also stated that in heaven no one gets married therefore no one has sex either.
This is to say that God created the physical body for very specific purposes in mind. God further emphasized and reinforced the separation between physical and non physical bodies by prohibiting the angels to become human for the purpose of sex.
The human sensible experience is contrasted from the spiritual one (although both are living souls) repeatedly in the scriptures. Both experiences are given legitimacy, as highlighted by the need to offer a perfect human being in the form of Jesus in exchange for an imperfect Adam. Literal physical red blood, not symbolic or spiritual blood, had to be spilled.
But we are to presume that in a burning hell this contrast is suddenly abolished?
