The point is that many people died, and at least one faced death rather than disclaim her faith. If it was that important to her, maybe it could be of value to others.

All religions teach a code of conduct that makes everyone more civilized.
That is why people should be not just more tolerant of other beliefs but actually should encourage, rather than seeking to obstruct, those practicing other faiths. Enter words describing a concept or keywords.
