We have proof that every intelligence in the world is working to undermine our freedoms, so it's easy to speculate (with some degree of certainty) that if others have their own agencies you need to have yours, to counter theirs.

What are those "freedoms", where is that proof, and what is the motivation of these "intelligences"?

I assume they do it because they hate American freedom.

The freedom of the people to chose their own representatives and leaders, something U.S. agency CIA has tempered with many times, especially in South America.

Or is the CIA that hates other countries freedom to not agree with them?

Maybe other countries created their agencies to defend them from CIA.

There are always two sides in a story.
