God his VA pisses me off. Reminds me of my father..... I hated my father.
Daddy issues aside, he really doesn't know the first thing about a synth, does he? Mainly that they aren't even robots. They are synthetic humans. Granted, the first two gens are more robotish, but last I checked they don't really have that much in the way of free will, minus the few who got injected with personality. And even then, if he knew the first thing about the Institute he'd know that they hate their freewill just as much as he does. So honestly, more than anything I question why the BoS hate the Institute?
The BoS hate the fact that the robits have freewill, and so does the Institute. Only difference being that the BoS want to commit genocide, while the Institute want to fix the problem. It'd make sense if the BoS wanted to completely overtake the Institute for themselves. But no, he wants them all dead to the point of pretty much setting off a nuke. The place wasn't big, you could've just killed them all personally you know!
