Soldato
With all due respect he's going to suffer no matter what he does and we don't have all the context. Even if he managed to get out immediate danger area there's a good change he'll get shot by his own side, crawl over the Ukrainian frontline he will get shot by his own side, if he's picked up and sent to a hospital you think the Russian doctors and nurses will trreat him any better? They'll patch him up so he can at least walk and send back to frontline.Anyone with a shred of human decency?
By all means drive them out, kill them if necessary, but you lose any right to claim the moral high ground when you deem it acceptable to inflict unnecessary torture and suffering.
BTW Ukrainian could have been assaulting that position, if he was still alive he could have got a gun and started shooting and someone could have got killed. His fate was sealed the moment he stepped foot in someone else's country intent on doing harm.
