Bhai the point of showing the humane side of terrorists exactly meant they're human too, and they are also taking those steps bcuz they had been through some shit. Just to be clear, I'm NOT supporting any fucking terrorist, I'll never. KILL THOSE MOTHERFUCKERS FROM POINT BLANK SITE.
But the point that the show was trying to make was, terrorists don't just kill people and be like hehe, gala kaat diya, maja aaya LOL. What Masood and Burger mentioned about losing their own people was a reference to what the USA did to their ordinary lives, helping them build Taliban and then started killing them like dogs. The show never nowhere justified their actions, but just shed some lights on what led to their actions and how they're brainwashed themselves.
And we people are literally not that chutiya who will think like bro this terrorist offered water to some passengers, so let's forgive them. No for fucks sake. Hang those motherfuckers as soon as you get the chance.
