morality can also be freeing, to the extent that members of a society are bonded to their social group and seek to protect both it and its members
through this protection, individual members experience the freedom to experience the full breadth of human emotions, including love, empathy, deep connection, etc, which require trust.
when no effort is made to socialize members into wanting to protect and cherish one another, individuals feel alone in the world, and like it is them against the world (everyone else), everyone for themselves. one becomes preoccupied with simply protecting themselves and their basic interests, and the luxury of the full breadth of human experience is lost, like being only able to see a few colors of the spectrum
and of course what is morality? and what is immorality?
people have a tendency to define particular group and their beliefs/ideologies as good or evil, but i think the essence of morality is, respectively, having and cherishing bonds with ones membership group vs betraying those bonds and any others one might have to other humans. it is in this latter state that people become immoral, in their thoughts, feelings, and/behaviour.
although merely being a private person who keeps their distance from others does not make one immoral, as such a person still cherishing the thought of being part of a social group and seeks to protect this, even if only just this thought as they abstain from any worldly action, because of the freeing psychological effect it provides them. it soothes their soul.
indeed, i believe this to be the essence of morality, for i have seen even islamic extremists exchange deep affections with their members, even after blowing off a prisoners head. in fact, it is these shared activities underlied by a common belief - which can change over time (what's important is that they are shared) - that appear to strengthen their bonds to the organization; were they to betray the organization and thus those bonds they would be considered immoral by their former group, now on the 'wrong path'. on the other hand enemy groups might consider them 'right', this is where the relativity of morality arises.
but what is universal is the condition that one cherish and protect membership bonds vs destroying them, regardless of the particulars of membership group ideologies, beliefs, values, etc.
