DEUT1149 It is forbidden to put it another person's life or well-being needlessly at risk. Thus, we may not keep a vicious dog or an unstable ladder in our home. If we do and they cause injury, guilt rests on our head (Ketubot 41b). Therefore, if we possess a broken or hazardous object, we should fix it or get rid of it. Rabbi Pinchas ben Yair would not enter Rabbi Judah's home : "The Angel of Death is in this man's house, and I should accept his hospitality?" (Chullin 7b). Today, such an attitude should prompt us to avoid attending parties at which drinking a great deal of liquor (or using prohibited drugs, which is, of course, also illegal) is encouraged, so that departing guests are at risk of being killed, or killing others, in driving accidents.
