Sorry, but is Russia or the USA the one most likely to kill Snowden? Oh, yeah, it isn't Russia, because Snowden avoids saying things that could trigger his KGB handlers to disappear him... Like denouncing a genocidal war of aggression against a neighbor, or the assassination of journalists and political opponents, or the repression of any opposition in the streets...
By leaking American info, Snowden painted a target on his back that can be reached by the USA and all allies with extradition agreements. That leaves him with very few superpowers who won't hand him over to the FBI/CIA and execution or imprisonment.
If I were in his shoes, I too would relocate to a superpower not allied with the USA and avoid getting involved in anything political over there.
