I can understand that, though I certainly disagree. I can respect a principle of proportionality -- I don't think it makes sense to risk a life life to stop a petty theft.

To my way of thinking, any evil you know about is your responsibility to fight. Or at least not cooperate with. Personal cost doesn't enter into it. I think sometimes life doesn't offer you a middle ground between heroism and cowardice.
