Jesus and the cross

According to Christian belief, Jesus died on the cross for the forgiveness of sins. What the bible talks less about is our relationship with sin. We should hate not ourselves when we commit sin, but hate the act of sin itself. In other words we should hate anything sinful and steer clear of it in our lives. After all, our sin hurts Jesus and causes him to suffer. So while this is a more serious take on Christianity I hope you all realize how important it is to hate sin and love Jesus. But what do you think about sin? Is this perhaps too serious of a take on sin?
