Years ago my sister was the token gentile in a very orthodox community. Someone there got into serious legal trouble when their child got sick on the sabbath, they wouldn’t use the phone to call for help, and the child died. As a result, my sister became the ‘go to’ person to make emergency calls, etc. on the sabbath.
That community breeched Jewish law when they failed to call for medical help for a sick child. It wasn’t just that they could breech the Sabbath to save the child, but that there is a positive ruling that they must do so. Their ignorance of Jewish law killed the child, not Jewish law. It must have been horrible for them not only to lose a child, but then learn their sin.
They had a strange interpretation of Jewish law. According to the principle of Pikuach Nefesh "[rescuing a] life in danger takes precedence over the Sabbath.". An applicable Biblical verse is "You shall not stand idly by the blood of your neighbor" (Leviticus 19:16)
A friend of ours had a very orthodox family living across the street. One Sabbath afternoon there was a knock on their door. It was getting hot in the house and they wanted my friend to come over and turn on the air conditioning. We found it odd that they were forbidden to operate the controls but were free to enjoy the benefits.
