As the article notes, several of the women to be executed have claimed they were effectively duped into coming to Iraq. Clearly, this is something that they would say anyway.
On the other hand, is it really so unreasonable that at least *some* of the "ISIS brides" were, one way or another, tricked into being such? I'm put in mind of a case that you also drew our attention to:

Before you point it out to me -- yes, I'm aware that the girl in that case was 13, but still, there are potential parallels. It therefore strikes me as inconsistent, to say the least, to have no regard whatsoever for this possibility in the case of "ISIS brides".
I also don't support capital punishment, especially when it's on such a large scale, and especially when it will leave so many children as orphans. I wonder what plans Iraq has for them.
