Ultimately, if you accept the evolutionary theory, you dismiss ethics, you don't have to abide by a set of moral codes, you determine your own conscience based on your own desires. You have no reason for things such as selfless love, when a father dives in to save his son from drowning. You can trash the Bible as irrelevant, just silly fables, since you believe that it does not conform to scientific thought. You can be like Lucifer, who said, I will make myself like the Most High.
