It depends on your ethical guidelines.

I think that working in weapon industries helps to maintain peace by deterring autocrats and dictators from taking over the world (and there are a lot of them right now, so it is absolutely moral and necessary to maintain strong defence force for democratic countries).

Efficient open markets are contributing to the world peace by maintaining interconnected world. It is difficult to wage war with countries you trade with. And financial service companies are contributing to the global trade and therefore world peace.

Oil and gas are a declining industry (however, there is a lot to be done there to help it decline safely and ecologically responsibly). Nuclear power, however, is absolutely necessary for energy transitioning and mitigating climate change.

Only adtech cannot be redeemed.
