Is science good or evil

Science is not inherently good or evil. It is a way to acquire knowledge systematically, which is only a tool.

The ways in which science is applied, on the other hand, can be good or evil. For instance, scientific research has produced dynamite, which can be used to do something evil, like blow up a school, or something good, like blasting a passage through a hill for a new highway.

There are many such examples. Nuclear energy generation / nuclear bombs, germ warfare / cures for diseases. Good and evil are in the actions of man, not in objects or processes.
