Well, sometimes I wonder how mentally healthy people are. Internet let me to see how bad mental health is around the globe, not only here.
I came to the idea that evil is the product of not being happy, not mentally healthy. A truly happy and mentally healthy person does not need to cause harm and he would feel fine when other people are happy.
We are being taught about being unhappy around the world, and media only confuses us. Hatred is the most extreme sadness that becomes rotten, because it was not properly treated in time.
In 5000 years you may not have currently existing countries, and probably our civilization might leave only a few plastic bags in a landfill, toxic and nuclear waste and glass bottles and rusty artifacts, and all these killings in wars or strikes of mentally ill people who kill inocents, will make no sense. Future archeologists may think we loved human sacrifices as we played videogames of killing people, and they will say we had a theocracy because we worship politicians as if they were gods.
