Matthew 18:2-6
He called a little child and had him stand among them. And he said: "I tell you the truth, unless you change and become like little children, you will never enter the kingdom of heaven. Therefore, whoever humbles himself like this child is the greatest in the kingdom of heaven. And whoever welcomes a little child like this in my name welcomes me. But if anyone causes one of these little ones who believe in me to sin, it would be better for him to have a large millstone hung around his neck and to be drowned in the depths of the sea."

Matthew 18:10
"See that you do not look down on one of these little ones. For I tell you that their angels in heaven always see the face of my Father in heaven."

Yes, there is a special place in Hell reserved for anyone who harms a child, that you can be sure of!!!!
I can assure you this is 100% certain.
