I didn't say anything about morality, nor about evil. As Rayiner has correctly noted more than once, in international affairs the world is ultimately a Hobbesian state of nature. Morality plays a definite but limited role --- especially when different people adhere to drastically different views of what's "moral" or "evil"(cf., e.g., Crimea), in which case the stronger side will win.
The brute fact is that a government that daintily claims to be morally "above" gathering intelligence about potential threats is one that likely won't be in power for long. By and large, the people in charge of other governments tend to know this. Apropos of that, note that the Fourth Amendment to the U.S. Constitution prohibits only unreasonable searches by the government.

Life isn't a snapshot, it's a movie. Other governments might not have particular tools now. If history is any guide, they will, soon enough (cf., e.g., the nuclear-weapons programs of various countries).
EDIT: BTW, I'm not the one who down-voted you.
