It matters a great deal, though you might imagine otherwise: my company makes bombs.

I feel that I make a difference with my work. I can see the results in the news.

Being unethical would include things like selling duds, billing the customer for time spent on other projects, colluding with competitors to raise bid prices, bribing the customer's people to choose us, stealing plans from a competitor, hiring unqualified family, and choosing subcontractors based on bribes.

Just ahead of graduation I think of my career path a lot. I feel, that I want to pursuit a career path that I will leave a good footprint in the world. Although I see a great culture in the software development community itself (e.g. open source software, Wikipedia), I would love to see more programmers with an idealistic drive towards society as a whole.

Ethically earned money and positive popularity among peers would be my main driver. I'd defintely like to create a few inventions here and there related in my niche for the betterment of society.
