From times immemorial, humankind, in its brief history on planet Earth, has caused and experienced for itself unimaginable horrors and carnage. Violence is commonly used to settle disputes or to gain advantage over others. This is amply documented and evident even today as I write. Not only have we humans annihilated the lives of hundreds of millions of other humans, but we have eradicated precious creations such as art, architecture, sculptures and monuments representing the finest products of human civilization, remnants of which adorn museums around the world. During this same brief history, humans have also demonstrated unsurpassable acts of love, kindness, mercy, empathy, compassion, forgiveness, sacrifice and benevolence towards others, and such deeds are evident even today. Hence, we confront a dilemma. We have evidence of the best and the worst behaviour that humanity is capable of.
