Jehovah's Witnesses: Why can't Jehovah make Armageddon be a smooth transition?

As you all know, the Bible describes Armageddon as a horrible experience. Everyone involved would be unhappy and traumatized. Why can't Jehovah ease us into the New World by being firm about the rules and enforcing them accordingly? Since there are a myriad of angels, each one could conduct a free in-home Bible/booklet study, and those who agree to go to Kingdom Hall would be allowed to stay in the Kingdom. In this way, it would be very simple to separate out the goat-like ones from the sheep-like ones. Anyone choosing to not become a publisher would be given a certain amount of time before they drop dead and dissolve into the grave forever. No cleanup, no worries! It all sounds so simple, so why are the complexities necessary? Isn't God capable of making things easy and stress-free for those who are nervous types?
