Just like terrorism, if the person saying "Let's kidnap a government official" is an FBI agent but you didn't know, you still decided to conspire with that idea. The reason the bar for entrapment is so high is that the societal expectation is that you WON'T DO A BAD THING, even if 30 CIA agents all offer to sleep with you or give you a billion dollars or prepare everything for you and you just have to sign a sheet of paper. You probably shouldn't conspire to kidnap someone, regardless of who came up with the idea first. You are expected to just not engage with the guy suggesting it.
