If either of these things were true would it justify the killing of Jewish babies or children? According to Sharia law, yes it would. According to the law of Moses, no it would not.
The guilt of one person cannot be transferred to another in any human society according to the law of Moses. The death of Jesus is a special case which does not come under this law.
Muslims complain about the doctrine of penal substitution when it comes to the death of Jesus but they use it all the time to justify their killing of children and other innocents.
All Muslims, including Paul Williams for example, believe, if they are true to the teachings of their religion, that if it required the killing of all Jewish children presently living upon the earth to force the Jews to give back their “occupied” territory then this would be morally upright and just in the eyes of their god Allah and his prophet Mohammed.
We are living in sad times. There are billions of people on the earth who are morally sick if they are true to Islam and other “your life is cheap and expendable if you are not one of us or you belong to an evil group as defined by us” or “the end justifies the means” ideologies. The future looks bleak.
