Tai Shang Gan Ying Pian

let's study part six of Tai Shang Gan Ying Pian.
Nos 3,
With brutality they do harm and damage.
Insidiously they injure the good and the law-abiding.
Stealthily they despise their superiors and parents.
Nos 4,
They disregard their seniors and rebel against those whom they serve.
Nos 5,
They deceive the uninformed.
They slander their fellow-students.
My view:
Some bad people always like to do cruel things to others or things out of greed, hatred and craziness. They always like to hurt others out of jealousy. They never show respect to their own parents, superiors. Their mindset totally do not have any elements of goodness. This type of people not only bring misfortunes to themselves but also cause a lot of troubles to the society and their own country and the whole world.
My dear friends, I hope you are not this type of people. If yes, then you have to quickly delete this type of corrupted mindset, do not wait any longer.
What is your view about nos 3, 4 and 5?
