If you do wish for that, believing in the mortality of the soul and that Hell can not exist (since that is essentially what you propose), then you are freely given the choice to reject God's gift~ I can't stop you! xD
As an actual response to prove otherwise tho, the Bible actually describes what you wish for as what Job also wished for in Job 3:13: "For then I would have lain down and been quiet; I would have slept; then I would have been at rest,"
For context on the Book of Job, none of the theology described inside is entirely accurate as it's a narrative with Job's "friends" near the start of the book being complete pro-life jerks, and Elihu (who rebuked Job and his pro-life "friends") being the only one whose theology is entirely accurate~ Job's theology is mostly accurate imo, but his desire for what he wants the afterlife to look like is completely wrong but does give us insight on how the Bible (or rather God) would describe such views! ^_^
However, imo, the verses you quote aren't really enough to justify such a belief~ Far from an eternal rest as described in Job, 2 Thessalonians 1:9 describes it as "everlasting destruction" and as a punishment. Everlasting (which means never-ending) would be an odd word to use to describe one ceasing to exist as well! xD
It took me a while to understand what you were getting at with Ezekiel 18:4, but I think I got it now! lol. You aren't confused about death being eternal but soul death being eternal, right? :)
Well, in the Old Testament, the soul is the person, not separate. This is best explained with the creation of Adam in Genesis 2:7. When God created Adam, He breathed the breath of life into him, not giving him a soul but turning him into a soul. This is why he is described as a living being or living soul in 1 Corinthians 15:47 (which would otherwise be odd considering how the New Testament talks about souls). This is also why the Hebrew word for soul, nephesh, is often translated not just as soul and life but as person and in reference to people.
