That's your perspective and it's perfectly valid to me, believe it or not. But it's just one perspective. The evidence I've seen has shown that their mission and the way it's prosecuted don't align with your perspective; that's reality and one should be cognizant of that.
It seems to be the modus operandi of the Cia. Approach an asset, cultivate him, exploit him and then dump him with zero regard to his personal safety. On top of that, they are very poor at keeping their spies identities secrets. Or perhaps they don't care.
The attitude you are trying to defend is incredibly arrogant and selfish. I don't believe other countries spy agencies treat their assets with such contempt.

They absolutely do. Why do you think otherwise? It's not like anyone really has sympathy for spy agencies assets, they are usually active traitors after all. If they weren't betraying someone or something they wouldn't be useful assets, so again it's very hard to drum up sympathy not only in the agencies but from general public too.
