Answer:
Science has caused some atrocities, however it is also solely responsible for the survival of the sheer majority of the population.
For example. A single ammonia producing process (for fertiliser) discovered by science is now responsible for feeding 40% of the worlds population. That is about 3 billion people sustained by a single scientific process. However modern weapons would not exist without science. Science has been mostly applied for good, however there are a large amount of evils as a result too.
Science is neutral, what matters is how humans have applied it.
