The hacker group known as the "Darkside" claimed that they had extorted millions of dollars from a number of large companies, but now they want to do something to "make the world a better place."
Why would we be resisting an effort of turning over a new leaf? If a criminal is in a process of conversion and in that process decided to give away all his money to charitable institutions to help others in need, would you say no to it? Would you discourage others from accepting the money that could be life-changing?
For me, I won't. Money is neither clean nor dirty. It is only as clean or dirty as how it is used. The money that is obtained by selling drugs is the same money that could send poor children to school. But that's not justifying the crime.
