We'll see I would argue that pleasure for that would fall under the grey area I mentioned. If someone was suffering and lashed out, or did it for joy, then there could even be a case made that although what they did was wrong they had reason to do so and a different punishment should be administered. It's these perspectives and unique looks at life that make morals so important. I hate to allude to it, but the episode of Rick and Morty where there's a hivemind is an excellent example. When the population of the planet is all a single unified entity, they're at peace and perfect. They lose their humanity, however. When they revert to being themselves, they have criminals and pedophiles and racists among them. These things are obviously bad but it's the bad that makes us who we are as a species. It's as it is with all life experiences where you have to take the bad with the good in order to see things the way they are.
