There are countless actions which could cause the death of others. Selling cigarettes, serving hamburgers, and driving come to mind. Some will value a state-mandated solution to these problems over the idea of individual liberty (including the risks of causing death to oneself or others). Some people will value the latter more. There's no one answer that fits every situation, which is how we wind up with peaceful societies than can take different approaches to solving these problems.
Personally, I think liberty is a more powerful construct than groupthink or group-forced behavior and actually leads to better outcomes for everyone than group-controlled plans or solutions.
