On the Inca King, Atahualpa, Being Forced by Pizarro to Either Accept a Christian Baptism or Die by Fire, Atahualpa Accepting These Terms, and Pizarro Killing Him Anyway (After the Baptism - the Baptism Supposedly Ensuring the Poor Schmuck's Entry Into Heaven) via Strangulation

Yeah, the Inca chief probably should have asked for more specificity, read the fine print, etc. (though, yes, the treachery of Pizarro would have probably made it a moot point - this guy being even worse than Cortes). Oh well, coulda', woulda', shoulda', I guess.
