Working for the enemy

I was offered a work in a company that works for banks, those damn thiefs. To add insult to the injury, they use Java as their main language.

What should i do? Do i sell my soul to the devil for the sweet bucks?

I don't get it, banks are your enemy and yet, you wish to help them prosper by offering your services? The answer is simple, you must either give up your infantile hate of all banks OR refuse to take the job.
