Science is powerful but, as you've stated, balance is most critical. It was one of the most impactful biologists of the modern era that wrote "the civilised races of man will almost certainly exterminate and replace throughout the world the savage races" based on his theory of natural selection.

As you can imagine, statements like these were used to justify the Atlantic slave trade, the genocide of indigineous people ie. "manifest destiny" and other colonial era horrors.

One should not treat science or the words of scientists as absolute truth. Unfortunately it is not free from human greed or corruption.
