I think he doesn't have a way to use all the money he stole. Hopefully all the money will go back to its original owner, not into someone's pocket. That hacker woke up one day convince to the right thing. He did the right thing. Dirty money will always haunt you on your sleep. It's not easy to do this stuff and he worked for it as well but the way he does it is not right. His conscience prevails. This only shows that there is a goodness in everyone's heart. Able to find courage despite the temptation is a good deed. BTW, will he still go to jail if he got caught?
