I have been saying precisely the opposite - namely that we all have the capacity to freely choose to do evil.
If it doesn't encroach on another person's liberties then yes.
This is begging the question.
I asked if the foundation of liberty was the freedom to evil.
Your response is that it is "if it doesn't encroach on another person's liberties."
You can't define liberty by using liberty as one of the terms in your definition.
You spoke of the "foundation of liberty" - I ask again, what is the foundation of liberty?
I'll point out that it cannot possibly be the freedom to do evil, because even in societies which are widely considered to possess almost no liberty at all - North Korea, Saudi Arabia - there is complete freedom to very evil things. In fact, the frequency and intensity of the evil done to people by their fellow men is a hallmark of those societies.
