Is there a heavenly reward reserved for all the murdered children that didn't get to exercise their Free Will?

As a child that was d and molested by several people, i never blamed God. "Free Will" not only belongs to the innocent but also to the wicked. God does not intervene because his understanding of the situation and yours are eons apart. The child is an entity incarnated into a human form, just as yourself. And the spiritual lessons of each entity varies. A child d, beaten and murdered will carry that experience with him on his next life because a spirit never dies. In his next life the entity will have developed empathy to abused children because of his own emotional memory of the ordeal,thus, a lesson learned!
