It is widely believed that the thumbs up gesture originates from the gladiatorial fights of ancient Rome, in which the destiny of a losing gladiator was decided by the crowd. Thumbs up, he lived, thumbs down -he died.
Hypothesis: Are the ones he gives a thumbs up with the ones who were bad but are now working with White Hats after a "gladiatorial" challenge by defeating another cabal agent?
Need some eyes on this one!
Yes we accept that the thumbs up meant lives, but that is more a construct or OUR current use of the hand signal, not theirs.
Actually in the time of the coliseum games, the signal meant just the opposite.
Thumbs up meant 'send his soul to the gods above'. and thumbs down meant 'leave his soul here on earth'.
FWIW
