This may be just a difference of perspective. It is noble that you prefer to fix it. I consider that "fixing" broken things is a task that adds value to the world. I think that value creation generally is something that is rewarded (not necessarily monetarily), and that "fixing" inefficiencies or loopholes in the markets is rewarded with money. I'm not sure what "exploit" means or why you seem to use "make money" as a bad thing. Society uses "automation" in a wide range of tasks that was not previously possible. In finance, like in other cases where we automate previously rote tasks, I think its important to check it, because bad code running on tight loops can have disastrous consequences.
