During human existence..we have been inventing different types of weapons, warfare that can warp us out of existence.  Each Year has their own pros and cons, when it comes to building weapons and testing it out on our enemies or the wastelands or in the ocean.  

During those years...there were different types of punishment that were put in place.  

For examples. 

The 1600 era was not the best year to be alive. 

The six million era was also not the best year to be alive..because of dinosaurs walking the earth. 

The 1700 era was also not the best year to be alive at those moments. 

The Ice Age era was also not the best time to be alive, because of climate change,  sea level and our planet was not yet stable and balanced during those years as it is nowadays. 

The last time..when the human population was close to existence..is when there were five thousand humans left at that time. 

Now imagine that one for a minute..on how close we were about to existence. 

We engage wars like it is nothing and we do not care about human lives being wasted on wars. 

During the 19th century, The government, and general were saying that world war I is the end of all wars but after world war 1 had finished..not so long for peace..because world war II was around the corner but before world war II could happened, the Great Depression took place cause damage to around the world.
