THE EVIL SEED WE GROW

What is right or wrong is determined by the society using ethical values and norms as a classifying benchmark. What makes up the society itself is households and social institutions.
If the above is agreed upon, we can conveniently opine that the fate of any society largely depends on what households and institutions teaches.
Human beings are meant to emulate whatever situation they find themselves. No one is a born philanthropist neither do we have a born sadist. Whatever we are today is taught/learnt by/from the society we dwell or through personal experiences.
A psychologist once said "give me 20 kids from which I will make a descent one; a robber; an assassin...." Our mindset and attitude is product of what we were taught or passed through in our lives.
Surprisingly, some modest family do breed highly immoral offsprings and we have seen good heads from the least expected homes. That is life showing its own drama.
I'm sorry to jump into conclusion, two of many evil seeds we grew overtime are racism and terrorism.
RACISM
Prejudice or discrimination based upon race.
That's life, pathetically the kind of society we find ourselves in.
Parents use verbal walls to create social classes via racial, tribal and religious differences and the poor children grow up hating without no justifiable reason and pass the unfortunate trend to their offsprings and the crazy chains goes on and on.
One of the reasons why the global society is in a continuous state of disarray...
TERRORISM
A psychological strategy of war for gaining political or religious ends by deliberately creating a climate of fear among the population of a state.

At times, I resort to some mental exercise asking questions like who invented gun(and other ammunitions) and why? The world would have been a semi paradise if we haven't grew excellently in developing life-taking techniques like nuclear weapon.
If we cannot control what is going on in the world today, we can at least control what is going on in our brain. This ability if used positively will definitely make planet earth a sub-paradise if not the actual Paradise.
Stay positive and stay blessed. Peace.
