Sex trafficking response

Sex trafficing has always irked me. It makes me upset to think that human beings can be so malicious. How desperate do you have to be to sell your own child for some pornography or alcohol? Do these people really love their children? Most mothers and fathers would die to save their children, and they would do anything to keep them safe. Do these parents feel remorse after they realized what they've dont to their child's life? It's not fair to the kids. They won't know how loved and treasured they are. These kids are precious just like any other, and they never deserved this kind of treatment. It hurts my heart knowing this is going on in other countries. If I had a child I would never let that happen. I would die before anyone put their hands on my kid. So what is going on in all the other parents heads?
