Nah all of sin are on the tentacle to brain list. I hate how the twins got turned into superhumans because of them, I consider it bad storytelling, and in my opinion it ruined their character.Shen also seems like a genuinely nice guy who believes most of the things he says. Shen, Briar, and Zara all feel like a found family that would probably be very decent people if they were surrounded by fewer manipulative jerks. It's probably important to them to rationalize how HERO is just as bad if not worse.
But regardless those fuckers laid hands on them, they die, the sooner the better.
Of course when we had the chance to kill Cole, he instantly got plot-armor, as I predicted. Because for the sake of more pointless melodrama in the future, he must live.
