What is the source of morality?

Morality is different for every people, because everybody is educated differently and the morals change in different cultures. Also while people grow up and start gaining expirience and start to grow and independent thinking some there morals change. You learn morals for the first time when you are a kid, and they are teached by your parents and family. This moral will depend in the family you are born in. For example in a family a kid talking in the table can be consider irespecful, but for another family this could be normal. Schools also influnce in the morality of a person, because when you are in school, the teachers make you read books that will have topics that influece in your opinion of what is right and wrong.
Like i said before morality can change while you grow up. A perfect example of this is when you are a teenagers. Most of the teenagers when they were kids were told that alcohol is bad, but when they grew up they learn that alcohol is bad if you drink it in a excess. Another example is when you are teenager and you start expiriencing life, and slowly you start meeting new people, and those people will influence you and they will express there morals, even thought you dont notice, some people can change your morals and this can be good or bad.

Terrorism

is inmoral because  inocent human beings are killed
Terrorism is define as "The use of violence and intimidation in the pursuit of political aims." Violence is not needed to pursuit political aims. So terrorism is not really needed. I think that killing inocent people to persuit a political aim, is inmoral and unnecessary. I also think that killing people to prove you are right, is not working, this is just causing more hatred between the people involve. Also i dont think terrorist should be proud of killing inocent people just to show they have power. In my opinion terrorist should look other ways to persuit there political ideas.
