I'd argue that in absolutes our morality has gotten worse.
Consider for a moment how we express our moralities; generally with double (or multiple) standards due to distinctions drawn in either ignorance or antipathy.
Example 1: A mafia enforcer. Ruthlessly obedient to his even more ruthless boss. Kills for money and personal satisfaction. Given to fits of cruelty. Loves his family. Is kind, gentle, compassionate, supportive. Genuinely cares for their well-being. Chastises his son for fighting at school. Always shows up at baseball games. Makes sure they get the best schools and private tutors and enough extracurricular activities. Is always supportive, but critical when need-be. Within the circle of his family, he might be a highly ethical person, a model father. In society in general even, he might be a nice man - good relationships with the neighbors, tips serving staff well because he knows how hard it is, etc., etc. But in at least one sphere of his life, he's a very bad man with very serious consequences for other people. Here the lines are drawn in antipathy.
Example 2: Our civilization, and everyone in it. Many of us are nice people, even wonderful people. We kindle and cherish moments of joy in our private lives - even sometimes, sharing such moments with strangers. We're considerate of others feelings and needs, and don't hesitate to do the right thing when called for. But, as it so turns out, we're also an accomplice in the greatest crime ever committed: the anthropocene mass-extinction whereby each one of us, by their daily activities working and consuming as tiny cogs in a vast, soulless machine, devours 30,000 to 140,000 species per day wholesale to say nothing of the irreparable harm done to others and environments as a whole which, one day not far from now, will culminate in the collapse of our life support mechanism and our death as a civilization if not species.
Here the lines are drawn in ignorance or apathy.
Our problem is that our means to effect change - positive or negative, have grown disproportionately with our ethical sense. And ethically, standing still on a treadmill is moving backwards.
I'm not by the way, saying that "barbarous" behavior one sees divinely sanctioned in the OT and such is, at all, morally positive and should be returned to.
