Perception or understanding has a lot to do with a person's desire. We have a desire to sin from the moment we are born, and that is natural for our understanding. The desire to sin leads us to choose sin because our understanding of the subject or perception of a belief system informs us in our understanding based on that bias. Sin is really the main reason our perception of everything comes from the irrational. And only because we know rationally that it is wrong to perceive something in a moral sense. We feel that despite our rational abilities, we still choose to do evil. So sin has a greater impact on our perception than on our ability to think.  

However, our past experiences play an important role in how we understand these life challenges. Since we are people with passions and physical beings with senses, we collect memories that are felt deeply and affect our understanding or perception. We develop habits based on our past experiences. All of these benefits bring us either pleasure or pain, so we avoid pain and are naturally attracted to joy even when the joy is false. Sin.Of course, in our past, although we rationally know that it is wrong, we love the pleasure of sin, and so we develop habits based on our love of the pleasure of sin. Sin really has a dominant influence on our desires. Irrational in our thinking and we teach our understanding to perceive evil.  

So our struggle with sin is the number one problem in how we perceive these things, and then our past experience has an effect, but it doesn't really make the desire to sin a greater need than the need to do good. Our past experiences influence our understanding, but sin is the main factor. If we think that past experience is the main factor in our perception, then we are pragmatists. In fact, we give past experiences more power than the power of sin within.
