On the flip side, why are you trying to condemn him for the same?
Because he said he was going to kill his wives and children? I am fully aware that there could be mitigating circumstance, maybe they do want him to kill them, but we don't know that for sure. I also find that conclusion that this is a smart move questionable, as the Taliban control a varying but large area of Afganistan, and the argument in this mand's favour hinges on the assumption that every man, woman and child in that area lives a fate worse than death, which I do not believe to be true. I am fully aware that this conclusion of mine is based off a limited understanding of the cultures of the region and likely coloured by my greater familiarity and preference for Western culture...
...however, all the information we have to go on is he said "I will kill my wife and children if I cannot stop the Taliban" He makes no mention of their wishes or any mitigating circumstances beyond the advance of the Taliban, so on balance, I'm going to take this ultra radical stance and say that that is wrong, based on the information available to me.
