Why do ppl say they don't judge (warning: this is long)?

All people have an opinion about life and people. It is not wrong to judge someones actions but it is wrong to judge someones self worth just because you don't agree with their actions.......that is the difference. Only GOD can judge the heart. Even when someone does something we think is terrible we must remember that we are still no better than that person....no body's perfect. So when you start judging someones self worth....that is when you are wrong....because GOD said nobody has the right to do that but him.
