I was taught that the harm done onto others is infinitely more grave than the sin that might be done on oneself.
If you read the teachings of Jesus, he never preached harm to others. That behavior is not Christian, but is blamed on Christians, by those who lower their bar. In reality, it came from a godless element in the Church, who sought the glory of their own ego. They lowered the bar, so they could play god on earth in their own time.
In modern times, aliens and UFO's have taken the place of God; modern mythology. These too would be defined as higher forms of life, that if encountered, would allow humans to raise their own bar and learn from them. If you think this is all imaginary, since there is no hard data, then the bar lowers, and all you have is the ego in an egocentric culture; rat race, where people define worth through materialism, money and power.
There is also celebrity worship, where people of talent are placed on a pedestal. The bar is raised and many people try to model themselves on them. But that is temporal and more for the ego and not the inner self. Celebrities come and go, with their moments in the sun, which may define a generation, and then disappear. The images of God in the various religion last, since they set the bar high enough to transcend time.
