Just define "care" I guess

Intentionally general. You could try and convince someone to change their diet, but you couldn't, say, force a change in Russian government. Not to say that all things out of a person's hands are that large scale though.

Things that are completely out of your hands. Is there a point in caring if you won't ever have an effect?

I'd say, if caring about futile shit took more energy than I can reasonably budget, then I'd say it's not worth it.

I don't think caring takes a lot of energy, though. It's the mere acknowledgment that something out there matters to you, and if you read/watch the news and discover that things are turning around for the better, it makes you feel good. It gives you a sense, whether rational or not, that things are gonna be all right.

If things are actually getting worse, then it may seem tempting to stop caring about it, because ignorance is bliss--but I'd consider that intellectual suicide. It doesn't seem healthy to me to live in such a blithe little bubble of safety and complacence--and like I said, it's not like you can't afford to read the news and feel something every once in awhile.

You mean things that are entirely beyond your capability to influence?

Only if you're content with greater suffering.

To an extent. Just because things happen that you can't control doesn't mean that next time it'll be the same case. I think there's a lot of things out there that can be controlled, with a few exceptions. It's just that most people aren't moved enough to really do what would be required to exert that control. It's important to care because if we don't believe we can control anything then we'll let everything else control us.

The amount I care is determined by how much it effects me or the ones I care about.

Yeah.

I may only vote for one constituent in one area of the country which doesn't influence how the government vote may be and which PM I get, but I care about what laws they make and how that will affect me.
