BA is one of those too big to fail. Tentacles spread all over legislators because they spread out their factories so they have more political influence. They are also in that permanent battle with Airbus, which the US sees as a bit of matter of national pride.

BA should have gotten nearly busted on the bs they pulled with the MAX. That is not an air-worthy plane. It should not exist. It's pure greed to have engineered it the way they did, and it's pure greed that oversight and legislators have allowed it to become the new norm.

In short, BA is looking to be on other side of the MAX disaster. If they survived what should have been a proper knee capping, it shows it's going to take a miracle to knock them off.

In light of that, I believe whenever the typical financial due diligence lines up to make the stock attractive, it's fairly safe to go for it.

What specific ethics concerns do you have other than the typical stuff you'd expect from a US corporation? That they killed a few hundred people with the MAX recklessness? The likes of Coca Cola and McDonalds kill 300k people per year. If you start making a list of killer US companies to avoid, it's going to be a long one.
