All strawman arguments and whataboutisms. You have no actual counterarguments.

Humans are animals and animals' main function is survival, which does not require morals. Hence, a human being does not need morals.

In the wild, the moral standards of civilizations would not exist because the overabundances and temptations of civilizations would not exist. So, no, a human being does not need the moral standards of civilizations to survive outside of civilizations.

Humans are naturally amoral. There is no such thing as objective morality, which is why everyone struggles to be moral.

Morality is a contrived set of standards that is meant to suppress human nature in order to get humans to be civilized; civilizations cannot function when their citizens are amoral. Hence, morality is pragmatism rather than a natural set of standards.

The damage that so-called immoral behavior causes to humans is ultimately caused by civilization itself.

For example, if there were no civilization, then there'd be no visual media and therefore no pornography; hence, one wouldn't have to struggle with porn addiction and suffer the mental health effects of it.

Another example is gluttony. In a natural environment rather than a civilized one, food is not abundant and is not readily available; hence, there is no opportunity to be gluttonous.

Morality is nothing more than a means of countering the negative effects that civilizations induce in humans.

Civilizations create an overabundance of opportunities, which is unnatural and which no species is naturally equipped to handle. Nature does not do this; nature's limitations induce balance in the species that live within it.

This logic applies to medicine as well. People who would not survive in a natural environment are able to survive in civilizations due to medicine, whether that be surgical procedures or prescription medication. The irony of this is that such people are subsequently able to reproduce, thereby creating subsequent generations of people who are dependent on medicine. Hence, civilizations then have to come up with means of supporting the increasingly burdensome need of medicine, such as publicly funded medical insurance or at least affordable medical insurance - which is a major political issue.
