What if, in the world we live in today, being "good" was not the "norm"? What if things were the other way around. What if, as a society people were imprisoned for doing "good"? What if doing "evil" was something to give praise for?
How would people's views differ and in what way would you imagine topics, such as are discussed in this forum, would be?
Just something to chew on.
It would be a nonsensical situation leading to the collapse of society. (In fact, not much of a society would be able to be constructed in the first place.)
Even among cultures that have been considered rather immoral by other cultures throughout history, they tend to still have some reasonable laws amidst their craziness, like don't steal, don't indiscriminately kill, and so forth. They do get some other things wrong, like limiting freedom, allowing sexism and abuse, or being excessively racist. They still provide themselves with a foundation to stand on, though, at least for a while.
If people were imprisoned for doing good, no legal system would even be able to stand, as it would be full of people who necessarily do bad things. Things like going to work, having a home, working together, and so forth, would be impossible.
