They were just puppets for Satan’s agenda. If they didn’t do it, he would have found others willing to do his bidding.
Everything is predictable in hindsight. We know these names because they were the names of the people that came up with the ideas and committed atrocities due to them.
Going back to kill them wouldn’t change a thing, the only thing history would remember are different names, but the same ideas would emerge and the same form of leadership would act upon them. Technology is an enabler of new forms of war. It will always evolve as the technology does.

It seems we’re ultimately responsible for the ‘beasts of the Bible’ to emerge...which is why it would always take time. This is why I do believe in some form of ‘ultimate event’ that will change the Earth forever...but it will only make sense in hindsight.
If ‘it’ is possible and we have the resources and motivation to create ‘it’ then ‘it’ will happen.
