Certainly not, but if we invent a life-saving medicine that 1 in 1 million people have a fatal reaction to, we'll still consider it enough of an overall positive for humanity to celebrate it as a technological win for society.

The ratio isn't 1:1 or even 1:10, but there is a line somewhere where X deaths <caused by new tech> is acceptable because of the X^Y lives saved <by new tech>.
