Early rockets (unmanned) were notoriously unreliable, so safety was paramount when designing for human spaceflight.

There will always be some probability of fatalities, and this is stated in the specifications: https://en.wikipedia.org/wiki/Human-rating_certification

The NASA Commercial Crew Program (CCP) human-rating standards require that the probability of a loss on ascent is no more than 1 in 500, and that the probability of a loss on descent is no more than 1 in 500. The overall mission loss risk, which includes vehicle risk from micrometeorites and orbital debris while in orbit for up to 210 days, is required to be no more than 1 in 270.

The initial failure report is out along with an onboard external video of the incident.

The abortive launch last month of a manned Soyuz mission to space was caused by a sensor damaged during the rocket’s assembly at the cosmodrome in Kazakhstan, Russian investigators said on Thursday.
