Freedom is not the license to do whatever you want to do, it is the always the ability to have chosen otherwise. So, if you chose to do right, you could have chosen to do wrong. Of course, if you have chosen to do wrong, you could have chosen to do right. Entire justice systems are built upon the principle that you are a responsible, moral creature.
The problem however, is that we have taken what is moral responsibility, and assumed a moral responsibility for our own happiness and salvation. We want to be our own saviors. So, we begin to dictate ways in which we or other humans can achieve satisfaction in life and eternal salvation.
The whole religion enterprise of human beings is an attempt to find salvation on human terms. And since you can never achieve true perfection, this kind of self imposed salvation can only lead to eternal bondage.
But there is Someone who can set you free.
