Although it should not be at the cost of safety but profit is the raison d'etre of any business.
I'm sure the victims of Boeings pursuit of profit with the 737 MAX would be physically ill at your assertion. Interesting your use of the term should. Airlines and airline manufacturer's are in the business of transporting millions of passengers every year. If they can't do it safely and still make a profit then they don't deserve to be in business.
