That is right. Bitcoin was created to solve the problems in our financial sector, but it never meant to harm or to use in illegal activities. It is up to the people using it whether it will be used in good or bad. And we cannot prevent or avoid those people to use it in bad since we all have our own free will to do as we please.
The future on how are we going to use bitcoin really depends to us. What people thinks about bitcoin, either positive or negative is the result of how people use bitcoin in their lives.
