What is the benefit of virus and hacker projects?

Question

What is the benefit of virus and hacker projects? Here I put a question mark about these projects that carry efforts to write and modify codes. Is it for money or just for fun or is a way of harming others and harming others. For anyone, do you think of working on a project based on building hacker and creating viruses for other programs? Some programmers like this profession and they spend the time, money and effort to do these evil projects. What do you think about these projects and do they bring money?

Answer 1

it depends
if you are an evil hacker, there arent benefits(maybe money but nothing interesting)
if you work(for example for the CIA), you are well paid and you help people.
