I think morality differs across cultures and time periods, and there's no absolute answer to what constitutes evil / immorality.
Things that were once accepted may no longer be accepted:
- Slavery
- Treatment of women as property with no rights or education
- Religious persecution
- Racial discrimination
- Blackface in entertainment
- Usage of the N word, see Agatha Christie's "And Then There Were None"
- Usage of "fag" to refer to cigarettes
Things that weren't tolerated may now be tolerated:
- Pre-marital sex
- Revealing clothing
- Nudity in media / Porn
- Divorce
I don't think there's much purpose to put a label on practices of the past, or practices done by different cultures.
People who do so usually just view things through their personal lens, and try to impose their personal beliefs on others.
But personal beliefs are subjective, and are not reflective of the absolute right and wrong of this world (a concept that I do not believe exists).
An example of time-based differences is Agatha Christie's novel "Ten Little N*****s", based on the nursery rhyme of the same name.
It was published in UK where the N word didn't have negative connotations at the time.
This title continued to be published in UK up until 1977.
After which I suppose the "N word is bad" spread across the globe, and the novel is published exclusively under its US title "And Then There Were None".
An example of culture-based differences in morality is the opposing values between Asian cultures and Western cultures.
As much as people on Western platforms criticize Chinese values, can we really say they're evil, immoral, etc?
In 2021, China's population comprises 18% of global population, whereas US + Europe comprises 14%.
If we use "majority wins" as basis, then China's morals are the "correct" one, and Western countries should start their own Operation Qinglang, mass surveillance and social credit system.
I think at the end of the day, our morals and "right and wrong" are what we deem it to be on an individual level, and largely influenced by our environment and upbringing.
In obscure communities, you will probably find wildly different norms.
For instance,
tribes who kill on sight - They might see it as rightfully defending their territory against trespassers, we may see it as unwarranted violence and straight up murder.
Same with
cannibal tribes, they do not see cannibalism as immoral or repulsive.
Wouldn't be surprised if there are rape cults where rape is considered a norm too.
