Reckless self-indulgence and bondage to sinful passions are simply not what God intended for human beings. Such behavior has much more in common with a dog than it does with God's design for us. When we indulge ungodly passions, it is as if we were sub-human, licking our own vomit or eating our own feces. These actions might be acceptable in dogs, but they are shameful and disgusting for people created in God's image. So it is when we are controlled by our ungodly desires. We were created for something much more noble than eating feces. We were created to have passions that are directed to the glory of God.
