Whether something is doable is irrelevant when it comes to determining whether it is right.
A separate question is what should we do, which is different from what is right. We should definitely do the most right thing we possibly can, but just because we can’t do something does not mean that it is any less right.
A real example: There’s nothing we can realistically do to stop much of the suffering undergone by wild animals through the predatory instinct. Yet the suffering of prey is very real and has ethical implications. Here we see something which has moral standing even though there appears to be nothing we can do to help the situation (beyond some trivial amount).
I guess what I meant is, what happens if what is right is not doable. This has been addressed below though. Thank you!
