That may very well be the case. But I think this is a distinct category of evil; the second one, in which you'll find most of the cigarette and gambling businesses, is that of evil caused by indifference.

"Yes, I agree there are some downsides to our product and there are some people suffering because of that - but no one is forcing them to buy from us, they're people with agency and free will, they can act as adults and choose not to buy. Now what is this talk about feedback loops and systemic effects? It's confusing, go away."

This category is where you'll also find most of the advertising business.

The self-righteous may be the source of the greatest evil by magnitude, but day-to-day, the indifferents make it up in volume.

I disagree. The health burden from smoking is approximately the same as death toll as the sum of all in the Holocaust, but smoking does it every nine months. And 1.3 million/year of those are non-smokers who are dying because they are exposed to second-hand smoke: https://ourworldindata.org/smoking

Even when the self-righteous are at their most dangerous, they have to be self-righteous and in power, e.g.:

  Caedite eos. Novit enim Dominus qui sunt eius.

or:

  រក្សាន្នកគ្មានប្រយោជន៍ខាត។ បំផ្លាញអ្នកគ្មានការខាតបង់

I think y'all are agreeing.
