To your first point, making someone unhappy isn't unethical. Making loud noise pretty much at all, is infringing on people's freedom. No one will bicker if you can't avoid the sound like starting a car, but if you play a loud TV it's unethical. Necrophilia is totally fine by this ethical standard, as it disgusting you is not infringing on your freedom (to say sleep, as the noise example). Pollution is a tough one, but trying to minimize it would be more ethical as it infringes on less people, etc. To your other problem, I fully understand the practical implications. Knocking the guy out and stealing his water is pretty unethical. However, coming to equitable terms is fairly easy. More humans can think one step ahead and just gouging the guy for all his posetions means he won't help you in the future. Long term, that is bad for you, thus you'll likely not charge too outrageous
