Why only ten commandments?

Moral Life

The short answer

Because the Ten Commandments are a synthesis of the natural law. Other sins are classified by moral theologians under the existing commandments — most of those you might add would fall under commandments four to ten, which concern how we treat others.

Where other sins fit

Moral theologians classify other sins under the existing commandments. Most additions people suggest fit under commandments four through ten, which deal with how to treat other people.
