My own thoughts - periodically we have a method of thinning the population, be it wars, or illness or disaster. These also send us challenges to make us improve things? I do thinks it's God's way of improving our way of living.
I don't think that God ^ends these things to thin out the population.
I believe that it is rather that wars are more likely when there are so many people that there is conflict over resources - food, water, territory, power etc.
When there are many individuals they live closer together, so illnesses spread around faster. In a technological era, people travel from one place to another, taking their diseases with them.
Natural disasters like earthquakes, volcanoes, meteor strikes and so on have happened to the earth long before there were any people (or even animals) to over-populate it.
Man-made disasters are just that - made by people - so they can't be blamed on God, neither can the natural disasters which are caused by what humans have done - the landslides caused by erosion after wholesale tree clearances, for instance.
It is too easy to assume that if something happens - good or bad - it is because someone, (or some God or Devil) has decreed that it must, instead of looking for evidence of what is the actual cause.
