A person's life is governed by karma and it is impossible not to obey it. However, free will allows a person to control their karma. Karma is a law, a love, a form, a system, a ritual, a wheel in which a squirrel runs. Actions and their motives determine a person's karma.
The meaning of free will is that a person can determine their own purpose in life. Having defined their goals and fallen in love with them, a person begins to learn them and learn, gradually rebuilding their internal structure for these goals. As you achieve your identity and your purpose, your life will begin to change in the right direction.
Don't judge, because it's pointless. I will tell you that everything is both good and bad. The more bad an entity is, the better it is... and Vice versa. Good or bad is a matter of your free will, your goals, and your personal choice.
The meaning of free will is that a person chooses his own goal (dream) and begins to grow towards it, entering the path of improvement. Initially, a person is perfect for their tasks, but choosing a new goal, they take a step into imperfection and get the opportunity to grow again, feeling the joy of endless growth.
