Your "right thing" is based on self-glossing publications that attempt to meld religion with morality. This is religion's "bulemic" mistake, much like the auto industry traying to include the kitchen sink and mother-in-law into calculations for EVs.Doing the right thing becomes a way of life, no fear, and it gets better over time. I wouldn't go back to my old life.
Christ's 'yoke' is easy, but may seem harsh at first, kinda like seatbelts.
This is where god's calculations prove that god is not that smart. No matter what, there's always a remainder left over after god has "finished" with the calculations. This remainder will include those who always already have morals not founded on religion, such as are found in atheism. Paradoxically enough, it is christianity that secretes atheism better than any other known religion of H. sapiens.
