Leaving aside the caveat "She would say that now, wouldn't anyone" this report illustrates one of the issues with expecting and seeking help from families and people about terrorist attacks. The headline:
Charlie Hebdo gunman’s wife had no idea he was extremist, lawyer says Saïd Kouachi reportedly kissed wife Soumya goodbye then told her he was going to Paris to see younger brother Chérif in Paris
Referring to the wife's lawyer explanation:
Hours before Kouachi and his younger brother Chérif stormed into the publication’s office in Paris, leaving 12 people, including two police officers, dead, the gunman kissed his wife, Soumya, goodbye and left their home in the Croix-Rouge area of Reims.

She doesn’t understand at all. Today she feels that she lived a lie. She had a normal life with a normal man, who didn’t show any radical views at home. Even after hearing the information, even after the police arrived and she heard what happened she couldn’t believe it. “I asked her if his religious commitment had evolved and she said he practised Islam, he kept Ramadan, he prayed at the local prayer place, but he didn’t proselytise. At home he was someone normal
