Why Will God Want To Burn 800 Billion People In Hell?

So far, the population of the world is 8 billion. The world has existed for 20 centuries and may still exist for another 5000 years. If you multiple 8 billion people in each generation by 105, it's assumed that around 840 billion or more people will exist on this planet.

Out of this population, only about 0.5 percent or less will receive salvation. So let's assume that the people who received salvation from when the world started till it ended are 10 million people, are we trying to say that the remaining billions will burn in hell?

I learnt from some teachings that hell is too large and can contain almost any size but what I don't understand is how God will intend to move such number of creatures to burn in hell forever
