Those above are true observations, and thanks for elaborating on your position.
And we've dwarfed this violence in the modern age with our mechanized wars fought for something ultimately devoid of meaning for those sacrificing their lives: bankers interests, profits, ...more material stuff.
People won't change- as we know and keep pointing out, there was the Cain affair almost immediately after leaving the earthly paradise. The hearts were hard but they didn't have the means to put that into practice, now good and bad actions have greater visible reach/effect. But yeah, I guess spear or sword wounds are better than white phosphorus and shrapnel, or nuclear blast burns and contamination.
In raw numbers it's worse in the present no doubt. Then again, when looking at proportions in the olden days a 100 or a 1000 killed people could mean the annihilation of your whole world (tribe or extended family).
What else can I say as to why I personally like living in the present state world more.
I think we have more options today than in the past as to how we want to live, whether it's keeping things simple or losing ourselves in the flow of the main current. I like the now more, although our genetic code keeps degrading I guess- Caleb was no weaker at 85 than at 40. I visited a gilded age mansion where there were 4 or 5 children under the age of seven I think, buried in a family grave on the property.
There was the practice of abandoning (exposing) frail infants in ancient Greece and Rome, leaving them for dead outside unless someone childless afraid to grow old without support took the chance and rescued them.
Then also in the time of Jesus, salt of the earth agrarian- which was maybe 90% of humanity, and city folk have heard that the gate is narrow and not that many were entering through it.
And I say much of the desire towards building all these things, even things like advanced surgery is control. People want control. They can't let go. Let go and just receive from God.
What can be added, God did tell Adam to subdue the earth, but of course there are many better and worse ways of going about it.
