If the state killed or tried to kill my friends/family in order to punish me for not doing what they wanted? Sure. At that point they've proven they're completely amoral and monstrous. This is something covered extensively by Invincible and other comics. It's not like this is some shocking original thought I've come up with lol. It's also demonstrated by real life - once people come to regard another as monstrous, they can justify doing whatever they want (c.f. present events).
Why not? Wouldn't you? You acting like this makes what I'm saying exceptional rather than typical is pretty funny to me, given how clearly most comic-book authors don't really agree. All of human history says that once the gloves are off, they're off, from prehistory to the modern day. The state killed your family because you, say, refused to go and eye-laser Tehran into the ground, or throw Jeremy Corbyn into the sun or whatever, would you just shrug and say "Well I'm not a killer, so I guess they can just keep on doing their thing!". I mean, incredible Buddha-like nature if you would but I'm confident most people wouldn't. Most people would consumed by emotions, principally hate and rage, and normally the limitations of being a human and living in a society stop them from doing much (though many parents dedicate their entire lives to doing what they can to find justice for those who harmed their children, for example), but a superman is not constrained by being a human, nor by being part of society (he doesn't even need to breath).
The other issue is, they just don't know.
You could be Buddha-natured. Or you could be your average emotion-propelled human. Your personality will be of insane interest to the state. The best way to control you will be to manipulate you by appearing to be your friend, not by being arm-twisting thugs.
