The person here represents the citizen, the visitor, the resident, the immigrant, and so on. The legal party also represents four types: the citizen, the institutions, the states, and the political parties, many of which are corrupt roles, and few are valid.

It is also used in all fields, and industries, such as projects, high positions, innovations, leaders of countries, famous personalities, thinkers, philosophers, clerics, etc., even in designs and systems engineering...

Roles are not limited to human beings and legal parties:

(1) Everything on the face of the earth plays roles according to the scenarios that God inspires it to sanctify. All of them are luminous roles, and the rare ones include graves.

(2) Any word in the language dictionaries in all the languages of ancient and modern science plays roles, most of which are luminous, but we have turned them into positions of hell.

(3) The things we make play roles according to the scenarios in which they are used. They play roles, most of which are devils, and the rare ones are light.

Humans have been in danger from the beginning, and it was relatively balanced over time, and we are now in real trouble. The evidence is found in the media, social media, institutions, parties, governments, and claimants of knowledge and knowledge everywhere on the face of the earth.

And everything became a danger, pain, and pain for all humanity. And we are making laws that suit groups of people that are inappropriate for other groups. And we accuse groups of different groups and eliminate everything beautiful, humane, and divine.

An Italian proverb says:

He who harms one person becomes a danger to a hundred.

The infliction of harm is done by the harmful and malicious roles of the person who caused the damage to another person who is the “affected.”

And so I say:

“And whoever harms a million people becomes a danger to 100 million people.

And whoever harms a hundred million people threatens all humanity."

Some examples, sayings, and judgments about the roles of "harmful" and "damaged" and they have other demonic and poisonous functions (Roles)

He who does not benefit from knowledge is not safe from the harm of ignorance.

Aristotle is a philosopher.

If money is the goal of those vying for power, there is no harm in it also being the goal of the unfortunate electorate.

Naguib Mahfouz, artist, writer (1911-2006).

Good is a voluntary action that leads to the benefit of others. Evil is a voluntary action that leads to harm to others.

Tawfeek Al Hakeem

A person can cause harm to others not only by doing but also by not doing; In both cases, he is liable to them for the damage.

John Stuart Mill

In promoting his interest, the individual may harm the public interest, and the nation may achieve the interest of a part of its members in promoting the general welfare.

Friedrich List

Environmental damage, such as graffiti, spreading flies, and littering, is a prevalent risk in inner cities and many urban and rural communities.

Margaret Beckett

Your worst enemy can't hurt you as much as your unprotected thoughts.

Gautama Buddha

We all inherit damage from the past. But, unfortunately, we spread it like a virus and don't think about it.

Thomas Norman DeWolfe

The more you have, the more people will want to use and harm you.

Lee Bo Na

Everyone was willing to take some small risks to minimize the damage caused by their ambition, disorder, and lawlessness.

Christine Kishore

You will ask - what does this have to do with software engineering?

Examine point number (3) and make it more clear. We build the software on the actor, not the role itself.

In my scientific view of the roles -

(1) Men and women are honored and strengthened, and everything is created for all humanity, and man is a faction of his own and does not belong to any other section of other beings, and everything we do (roles) for man.

(2) A person can choose the beliefs and sects (roles) he believes in or belongs to as long as he does not harm others.

(3) Human evaluations are based on the wrong criteria and unrelated to the well-done roles. Therefore, we need to look at how we evaluate humans based on their roles and not based on the human themself.

We will address everything I mentioned about the roles in this article and examples, sayings, wisdom, divine religions, positivism, etc.
