I wouldn't set the law aside. Do philosophy over the ethics if you want, but only after you are sure to have the legal side covered, because this one can ruin your finances and your life in general.

Unless you're based and incorporated in Iran, Iraq or North Korea, your country has signed the Berne Convention and has implemented in law some level of copyright protection that almost certainly makes the distribution of those books illegal.

If you're not taking very careful technical and legal measures to remain anonymous, you can get in serious legal trouble for breaking the law.

What is the upside for you? Companies like Uber, Google, etc break the law all the time. But they profit billions from that and then pay millions in fines and lawyers. What's your game? Are you profiting enough to make sense - financially-wise - to break the law?

Last but not least, I wouldn't play with lawyers' personalities trying to make them "please" you. Respect them, otherwise, they'll do whatever they can to make you regret it. And believe me, they can do a lot against you. These people are evil. Don't cross their paths.
