I've been on this earth for quite a while now, and yet, i haven't seen anyone to truly crave for peace(even when there was war)
It is true that our nature is about the way we perceive:
1. Crave food when you're hungry
2. "I want sun" when there's rain.
3. Some rain would be nice "too much sun"
And so on..
But what truly war is? War is a battle that "WE" as the population have nothing to say about - it's always about the people in control and how they decide it to be. Don t get me wrong, those people that control are also being controlled(Let's not get to deep where we might argue for nothing) BUT, the point is - War is just the weapon of control.
War brought way too many deaths, changed people... for what? For the sake of the fat pigs leading -_- and let me tell you some more: True peace cannot be achieved right now.
The people have gone in the wrong way "nowadays" the so-called "evolution" isn't an actual evolution, is more like our brain got smaller and we can only exist by using certain tools: Phone, tablet, pc, SO MANYY.
When will peace be achievable? When we all die. Why? Because we're the poison!
