Where do you find your standard of right vs wrong? Is it just what feels right/wrong at the time? Most likely, if that's it, you are just going by your early formation, which was likely based on what Christianity teaches is right and wrong. What if you didn't have that formation? What would be right and wrong then?
You don't need to have religion to develop a moral framework. Read about 2000 years of philosophy. Most of what Christianity teaches as morality was adopted from previous religions or even pagan philosophies.
Christian tradition itself is full of conflicting moral codes. Look at the new and old testaments. Or the behavior of most Christians versus the teachings and examples of Jesus.
