From observations of daily life, and in terms of consequences of their actions (karma), human beings may be classified into four categories:
1. Those who were born to cause harm and suffering to a number of people,
2. Those who were born to cause harm and suffering to a great number of people,
3. Those who were born to benefit and bring happiness to a number of people, and
4. Those who were born to benefit and bring happiness to a great number of people.
First, there are some whose existence causes sufferings to themselves and others around them (their family and community members, such as parents, siblings, friends, neighbors....). They bring pain, worries, and unhappiness, both physically and mentally, to those people for a short or long period of time, or throughout their lifespan. Human beings belonging to this first category, of course, have very bad karma. So do those who are in contact with them. Since both sides share the common bad karma; they get together in this life to reap the whirlwind they once caused in some previous life.
Second, there are human beings who, at some point in their life, cause massive destruction and unimaginable calamities to a great number of people in the world. They may be bomb or weapon makers and producers. They may also be famous scientists and scholars, high-ranked officers in the army, and policy makers, business or political leaders, who made the wrong choice or devilish decision at the wrong time, or who are overconfident, and so fanatically obsessed with some belief, doctrine or ideology that their decisions cause avoidable and meaningless deaths to millions of people in their countries and in the world. History has proved that such beings sometimes appear and threaten life and civilization on earth.
Third, there are those who, since their birth, bring peace and happiness to those around them for some time in their life or throughout their whole lifespan. Their parents and siblings enjoy their presence, as they always bring joy and happiness to surrounding people, and to their local community. Such beings have very good karma, and so do those in contact with them. Their appearance benefits others around them.
Finally, there are some, though the number of such people is small, human beings whose existence on earth brings joy and happiness to a very large number of beings, and not just for a short period of time, but for thousands of years, not only for one country but for the whole world, benefiting not only the rich and the healthy, but also the poor, the abandoned, and the sick.
