Nikola Tesla was a genius physicist, inventor and electrical engineer of the 20th century. He is most famous for having invented the alternating current (AC) electrical system, revolutionizing how we generate and distribute electric light and power. He lived in times when human ignorance reached its heights and people were pitting against each other to outsmart their competitors. However, the behavior Tesla tried to map in this quote is not real. Hatred by nature is not a human trait. In reality, it is nonexistent.
Hate per se is not a characteristic of human beings. It is the fear that gets manifested as hate, and any human being can validate it. When cultures because of incomplete understanding handout cruelty as a way of life, human beings feel bad from within and over a period of time the new generations get rid of that practice. Every individual wants to love and be loved. The default setting is of love and belonging in all human beings.
