> Judeo Christian morality was always rooted in a fear of God
The Great(est) Command(ment) is "To love God with all your being, and then love your neighbor as yourself."
Society improves a little when someone chooses to not do bad because they're afraid to get punished.
Society improves much more when someone chooses to do good by having evolved their sense of ethics and self-control.
Our most important human ability, and the reason we have a {moral compass, mind, and free will} is our ability to self-evolve our ideals, attitudes, and behaviors out of the selfish and animalistic towards the compassionate and humanitarian.
Our Creator loves us and prefers us to live in peace and prosperity, but we must choose to implement such a societal system that better rewards virtue and minimizes the harms caused from vice. And such a system must be our choice (i.e. democracy) because there must be no compulsion in religion (which pervades life as an ethos of compassionately positive contribution to the whole).
> As the belief in God has warped and wained away from biblical moorings, we shouldn't be surprised that morality has gone with it. To such an extent that, seemingly, moral character has very little impact when evaluating leaders, as long as other ideological boxes are checked.
Yes, that is indeed the case, but Christianity is no more or less guilty than most all of the other religions, their majorities taking the selfishly divisive road over the compassionately unifying road.
> it seems that these kinds of people are always present... in all times and all cultures.
As we live and breath, my friend. We are each those people, to more or less extent as per the predilections of our individual nature and those of the cultures we inhabit. The key is that we all(1) have the power both how to learn to be better as well as to choose to be better. [(1) There are the mentally ill and physically damaged and developmentally disabled folks that do not have the power to control themselves, but they are very rare.]
The universe helps, though, in that the human-only Law of Karma determines our happiness or unhappiness by how we have treated others. It is the applied aspect of "You reap what you sow." It is our environment's feedback system to let us know if we've been naughty or nice, whether we are headed in the right direction or not.
> So maybe there isn't so much uniquely bad about our current times?
Not for individual human beings; vice is vice and virtue is virtue and we have many inertias against our becoming better. But our technological progress has facilitated greater destruction to the Earth via war and pollution. It drives a more efficient systematic greed that oppresses the poor more brutally, and the rich have used their power to hire attorneys to craft the laws that let them rise above other human beings like royalty. The codifying of the MBA ethos that changed the "personnel" department into "human resources" is quite the tell.
