I once worked on some software that generated PDFs of lab reports for drug companies monitoring clinical trials. These reports had been tested, but not exhaustively.
We got a new requirement to give doctors access to print them on demand. Before this, doctors only read dot matrix-printed reports that had been vetted for decades. With our XSL-FO PDF generator, it was possible that a column could be pushed outside the print boundary, leading a doctor to see 0.9 as 0. I assume in a worst worst case scenario, this could lead to an misdiagnosis, intervention, and even a patient's death.
I was the only one in the company who cared about doing a ton more testing before we opened the reports to doctors. I had to fight hard for it, then I had to do all the work to come up with every possible lab report scenario and test it. I just couldn't stand the idea that someone might die or be seriously hurt by my software.
Imagine how many times one developer doesn't stand up in that scenario.
This is why I made that point, similar to you I would not stand for having my code in something that I can't stand behind, especially if it potentially harms people.
