We here in Belgium have had our share of child murderes, (1 (http://en.wikipedia.org/wiki/Marc_Dutroux), 2 (http://en.wikipedia.org/wiki/Michel_Fourniret), 3 (http://en.wikipedia.org/wiki/Murder_of_Nathalie_Mahy_and_Stacy_Lemmens)) but almost no one is crying out for the death penalty, only for a better working police and justice (because police searched a house where two children where locked up in a basement but didn't find them and because different departments didn't exchanged valuable information)

Anyway, children have to be protected of course, but that doesn't mean abusers have to end up in a gas chamber, only kept away from children.
