Pornography feeds lust of the eyes and lust of the flesh, which are never satisfied. It leaves the viewer craving more and more in order to achieve the same "sexual high." It easily enslaves people to their own cravings and opens the door to other forms of evil, like anger, abuse, violence, hatred, lying, envy, compulsiveness and selfishness. The power behind porn is revealed when the porn addict tries to stop their habit - it is virtually impossible without help.
Pornography sexualizes the viewer's mindset. It warps and perverts their perspective such that sex is unnaturally elevated in their thoughts. Porn's images are stamped into viewer's brain with the aid of hormones released during sexual arousal.
