Depends on the circumstances. For example, there are a few auto accidents where a person is thrown clear of a wreck, and saved by not wearing seatbelts. That's the "nothing" in this example. And there are cases where the wearing of seatbelts killed a person.

However, there are far far far more accidents where seatbelts SAVE people; where seatbelts prevent death and/or serious injury.

In this example, even though "something" (wearing seatbelts) has harmed a few people, "nothing" (not wearing seatbelts) has harmed far far more.

Good point in many circumstances ☝
