Some points of Lal which I overlook:

Now if the children really were zombies, wouldn't their mothers also be 'zombies'?

I haven't made my question clear: it is a general one, where the mother - the judge - maintains independent judgement and her morality. The consequences of letting the children live are those that I mentioned. What is your answer?

My friends' nephews play at being Orcs

I actually like the orcs of the Warcraft world. Not all orcs in all fantasies are the same. Some of them are examples of courage and nobility. The point in question was that those children were doing evil acts, which later would lead to a satanic cult at least for some of them.

the Valar had told the Numenoreans that if they broke the Ban then they would never see Numenor again

Hm, where is that stated?

If Eru was in the business of punishing anyone for consorting with Sauron then what did he do about those Men on Sauron's side who lived in huge numbers in Middle-earth?

Same problem I raised to davem: Numenor made a very powerful impact on the balance of power in M-E. Without it, the other black numenoreans were far less advantaged and in a lesser position to pursue the same evil goals - their problem was more than half-solved. Plus, those of M-E did not suffer Sauron's marring, at least not continuously/increasingly.
