I get what you mean and it's a case by case basis, if people didn't try and push any morals we would all live in vacuums where all we have is the law to tell us what is _right_.
A lot of people have no problem with their countries governments manufacturing and/or selling arms to dictatorships that inflict harm on innocents and supply extremists e.g. UK-Saudi arms trading. As far as some are concerned the UK is just doing what another country may do instead.
Because that's the only way to solve moral co-ordination problems?
If you leave a morally odious contract on the table (lets say it's cutting up human babies for baby veal) knowing your competitors will take the project, enrich themselves, expand, and develop the capacity to engage in larger, even more odious business, then what's the proper course of action?
Do you cut up babies because fuck morals? Or do you try to get no one to cut up babies? What if you have imperfect information and aren't certain if your competition would do it? What if they have imperfect information about your intentions and decide to take the deal purely on that basis?
Should be straightforward to recognize how corrosive this cycle gets.
EDIT: some people seem to be upset with the baby example. Just exchange that with anything you find clearly morally unacceptable. Like selling reverse mortgages to elderly people with limited capacity, or signing people up for ponzi schemes or adding intentionally addictive additives to a harmful consumable product, etc.
I mean, all I'm trying to say is that most companies are subject to the competition pressure in their market regardless of internal employees' morals, and it becomes hard to justify "standing up for your beliefs" in a business sense that isn't just "shut down the business or change industries," if there are inherent moral issues in the current industry.
When I say "have no sense of morals," I'm talking about competitors who were acquired by large PE firms a decade or more ago and do not have any internal discussions about the morals of what their employees are building/maintaining. They operate entirely by asking what clients want and then trying to build what they can of those requests.
I'm mostly talking about incentives and market pressures, not "imposing morals on others" or other such emotional nonsense that you are reading into here.
Your morals are your own? Why do you insist on imposing them on others?
