This girl was groomed. From before the age of 15. She was a kid.
You are down playing those who are raped, she actively sought out ISIS.
Unfortunately, those children were the product and casualties of a war she chose to be a part of. She may have been young, but when you're 15 you still have enough of an understanding to make a choice of that magnitude.
If ISIS didn't get their arse handed to them, those babies still would have died and we wouldn't know about any of this because she wouldn't have tried to come back.
15-year-olds do stupid shit like getting a tacky piercing or skipping English to hang out with friends.
Joining a terrorist that was widely known org and front page news known for brutally torturing and murdering, raping, kidnapping, keeping slaves etc etc at the time she was somewhat self radicalising is not on par with being groomed.
Especially when joining said org means you have to travel thousands of kilometers through multiple countries. It's not like you got forcefully picked up/persuaded at bus stops/outside of school plied with drugs etc etc.
I can feel sorry for her loss and still hold her to some personal responsibility, remember the initial outcry was that we had to take her back due to international law, we followed that.
