This man is clearly a very broken individual in need of treatment. But he still murdered a great number of already, by accident of birth, unfortunate women and children. Their relatives aren't going to sympathise with him at all and it's probably knocked the whole coalition off what remained of the moral highground out there.
Nobody has won here and nobody can win, short of the locals being permitted to see him being beheaded on a football pitch. That's not going to happen.
What a tragedy this whole intervention/war/conflict is in terms of material progress at home and here (money spent), morality, international common understanding and acceptance of each other and - obviously - lives.
The history books will not be positive or polite about any of this mess.
