I mean math is the backbone of science and technology. And technology can lead to fucked up things.

Nuclear bombs wouldn’t be possible without fairly recent math.

Not to mention the unethical hell that is the whole financial sector / trader type where mathematicians often end up working.

And finally these days, by making new discoveries in some fields your directly contributing to the growth of AI and LLMs.

An infamous example of someone who quit math over ethical concerns (ironic given the rest of the story) is Ted Kacyznski (the unabomber), who saw math as leading to more and more advanced technology which oppresses people and destroys nature.
