Debt is debt, you have to pay up anyway.
I don't care what you plan to use the money for, just pay back what you lend and you will be free, stupid people take loans and spent it on stupid things while the rich and smart people takes loan and use it for a greater course that could benefit them in future.
Still, even if you use loan money to invest in good business there is still a risk, the business might fail and been in good debt or bad debt will be meaningless, because a debt is still a debt.
