I am well aware of all that, and I have great respect for those people who made those sacrifices, but it doesn't make sense to
require that. The idea you're promoting here is "If you won't volunteer to have your life completely ruined, don't do the right thing. I'd rather you just be complicit in something that harms me if you aren't willing to be punished for doing the right thing."
Do you not see how completely bonkers it is to look at somebody who has already given you valuable information at great personal cost and demand that he suffer more for your benefit? Why on earth would you feel he owes that to anybody?
