Religion-justified murder?

Voltaire famously said:

Those who can make you believe absurdities can make you commit atrocities.

Religion can justify anything, even murder.  A controversial book, The King's Torah (written by two rabbis) argues for the killing of non-Jews in certain circumstances:

• The prohibition 'Thou Shalt Not Murder' applies only "to a Jew who kills a Jew" [cite]
• You can kill those who are not supporting or encouraging murder in order to save the lives of Jews
• Babies can justifiably be killed if it is clear they will grow up to pose a threat

Moshe Cohen, the spokesman for the Israeli Justice Ministry, described the book this way:

"You open the book, and you feel that you read a halachic book. And it's a trap," said Gadi Gvaryahu, a religious Jewish educator who heads the coalition. It was, in fact, "a guidebook [on] how to kill," he charged.

I'm not claiming that all religionists support murder, or that all Israelis support murder.  I'm saying: here is an example of religion being used to justify murder by two rabbis.  They're reading the same Torah that I'm reading, and concluding that murder, in certain circumstances, can be justified.  I can't comment on their arguments as I haven't read their book, and I'm still working my way through the Torah.  But even if their argument is sound (the Torah can be used to support the idea of murdering non-Jews), this still amounts to religion being used to justify murder (including of innocent babies).

My counter-assertion: my humanist-based morality is more sound than their religion-based "morality."  I do not advocate for the killing of innocent babies.  The idea that religion-based morality is preferable (or that morality requires religion) is such an indefensible joke.
