This may upset some people, but I think you have to come up with mental demarcation for responsibility, or you’ll go nuts.

I simply cannot decide to avoid all the technology of my field because whoever designed the electrical infrastructure didn’t do it responsibly. Or because the handling of ewaste hasn’t been dealt with. Or because everyone sourced materials in unethical ways.

My responsibility for most of that kinda ends at my voting behavior or trying to make reasonable personal decisions that are well within my small sphere of influence. A problem domain that I can handle.

Anyone who watched The Good Place knows what I mean. It’s not absolution for my own behavior, it’s just not holding myself accountable for everything that everyone else does… badly.

Otherwise there’s just no sword to fall on that’s big enough to feel at peace with the world. (Think of the snails!)

You are responsible for the reasonably foreseeable consequences of your own actions.

I'm not going to point to a TV show about alcoholism to substantiate that. You don't need me to. It is also why manslaughter, though a lesser crime than murder, remains a crime.
