Where do you draw the line on investing in companies that are “bad” or by making moves based on events like war?

Me personally I have yet to find a line I won’t cross.

My biggest holdings include many defensive companies such as Lockheed Martin and Palantir and I am quick to react to negative news but I was wondering what you all do. I don’t find that there is anything particularly wrong with this style of investing as to me the main point of investing is to secure the most money possible in as little time as possible.

Many people seem to be upset that people are choosing to invest heavily on defense and oil stocks as a result of this war but I’m failing to see the point of why someone shouldn’t do this.
