Replace "paper" with anything else you consume in your everyday life. I know it's an unpopular opinion, but to me, if there's something offered to you for a certain price, and you're not ready to pay that price, the alternative should be to either get something comparable that's cheaper (hardly possible with scientific papers) or, unfortunately, abstain from getting that thing at all.
I don't see how "what they're charging is ridiculous, and the money isn't even going to the authors, so it's okay for me to get the papers through sci-hub" is morally justified.
Independent of the above: if it's for work, your employer should pay for the paper access (unless you're self-employed, of course).
