That’s not brainteasers or evil, there’s a fucking wall of text of nuance in front of you, you should read it. He’s not saying it’s good, or that it’s right, he’s saying it’s smart to leave.
If you want to live, with the best chances, leaving makes sense.
If you want your children to grow up somewhere where they don’t fear for their lives, leaving makes sense.
If you don’t want to be subject to the attacks of a hostile nation that is basically mandated to be directly next to you, leaving makes sense.
It’s terrible, I would hate to have to leave my home and the place of my community due to violence. But I am not so attached to any piece of land that it is worth more than my life or the life of my family. If people choose not to leave, I understand the reasoning, but I still believe it a safer and smarter option to leave.
