I can't speak for all of security, but my experience is that they will do everything they can to preserve both lives, and both of their rights to live freely. They'll do everything they can to save your brother and Iniss.

My family is pretty big on preservation of life. I'm pretty sure my brother won't let anything happen to Tom if he can stop it. Iniss either. There are ways to keep Iniss alive until they can figure out a way to let him exist without enslaving someone else.
