I'm going to guess that you don't work on safety engineering. All safety designs have tradeoffs. Airbags can kill you but we still use them because the probable benefits outweigh the risks.
Airbags do not kill people. There were fewer than 300 airbag-related deaths of the course of two decades, and the vast majority of those deaths were caused by not wearing a seatbelt.
Frontal airbags, generally speaking, make people who would've died survive and make people who would've walked away with nothing look like they went a few rounds with a professional boxer. It's a flattening effect.
