When you build a new house, you shall make a parapet for your roof, that you may not bring the guilt of blood upon your house, if anyone should fall from it.
#deuteronomy 22:8 #kiteitzei

The law about building a parapet on your house illustrates a broader principle: resources and accomplishment bring responsibilities. If you are aware of a hazard that is under your authority or control and don't fix it or warn your brother, you might as well have pushed him.

If someone gets hurt through stupidity, it's his own fault. If you made it easier, it's also yours.
