Now this is a Problem with Atheism, You are Correct when you say "...you make your own purpose and give your life its meaning" - because this is the true essence of atheism which is Individualism. In individualism, the meaning and the basis on what is right and what is wrong is Based on WHAT INDIVIDUAL thinks. It sound safe and OK IF and only IF we are only Talking about your self. Because i believe you have Goodness in you.
BUT what if other people USE the concept of individualism to do other things? What if other people exercise the concept of individualism and say, Eliminating other people that block my success because it can DO GOOD for me? Since what is good and bad is based on What i think?
If we are going to remove the concept of God and adopt individualism, we will be in chaos and worst, theres no way we can Judge other people if they violate our freedom because after all, the basis of what is good or bad for us is based on What we think..
