Really? Let me introduce you to the Firestone Tire Controversy, where executives knew their tires were responsible in the auto accident deaths; they calculated the cost of doing a recall was more expensive than paying out compensation to families and decided to not do a recall, resulting in even more deaths - until they were finally found out.
Companies will abso-fucking-lutely murder and let/or let people die preventable deaths for profits. Sometimes, executives even go to prison for it (3 confirmed deaths in that case).
I don’t know about the Boeing cases, but I do know you’re naïve if you think executives won’t murder people for profits.
