there are three level of people around the world
the first one is normal one who are courteous and kind .they will give you favor back .say thanks once you help them out or remembering your favor .but they want favor back too once they favor on you .its just like human nature.
then there is one more kind below human ethics.
they are arrogant and sure they take things as a granted .they insult people for their own happiness like sadist .they think they are chosen one or deserving the best they think rest of the world are rotten insects .if you do favor to them they don't give your favor back or say thanks as they think they deserve it.they don't even care about people around them .that kind of people create domino effect in society of cheating, dishonesty ,rudeness and disrespect .
there are one more kind of people they are above human ethics
there work is just for god ,they want favor from only god.they help others without expecting any thing from them.these people are out of jealousy,grudge,or anger .they do their work very quietly without any expectation from this world .they are humble quite,respectful and patient .there all work and there all act is for god and happiness of god .they are true human .
