The difference between morals and social expectations can be described as follows:
Morals are a set of rules that all living things have found to be necessary for survival. For humans that equates to health and happiness.
Social expectations are a set of virtues that society members have learnt to be necessary for the purposes of social harmony.
Morals can also be described as principles of behaviour that are considered essential to the individual's survival. These would include rational thought, honesty, justice, independence, integrity, productiveness and pride.
Social virtues can also be considered as qualities or characteristics that are valued and appreciated by a particular society or culture, and are often based on beliefs, customs and traditions. These usually include traits like charity, compassion, compromise, fairness, forgiveness, generosity, kindness and loyalty.
Social virtues are always required when you live within a group or society. We learn social virtues from our environment, parents, teachers, friends and from the laws of the group.
Social virtues like LGBTQ+ rights, mental health and social justice have matured immensely in the 21st century and they reflect an ongoing evolution in social harmony.
Another new Social trend is called Cancel culture, which has sparked significant debate, with critics arguing that it can lead to a stifling of free speech and causing a culture of fear to express opinions. Supporters however, see it as a way to hold individuals and organizations accountable for what they deem as harmful behaviour. These supporters are usually Woke Activists.
An economic 'Safety Net' is an example of a Social virtue which enhances social harmony. All communities have some members who cannot look after themselves for numerous reasons including disability and old age. Traditionally this was handled by the immediate family members who would standup and help where required, but more and more these days, society is asked to provide community supported services for people that are in these impossible situations.
We all need to feel proud of our ability to consider and help others when it's possible or obviously necessary. I know we would like that kind of help if or when we required it.
Yes, we do usually live in a group or society and therefore these social traits do become a logical part of Ethics, but only while the individual prefers to continue to live with the chosen group.
When the individual changes to another group, so will some of the social virtues, especially if the customs of the new group are different.
When the individual goes one step further and decides to opt out of society all together, all the learned social virtues become irrelevant for survival.
If an individual's moral code is contradicted by a social virtue held for the sake of social harmony, then a dilemma exists which needs to be resolved.
It's the moral code that is the basis of ones life and therefore survival.
