That was funny ; )...
 Though you need to ask yourself if a Predator is a hunter, and hunters do hunt creatures like deers which do not have natural "weapons", would the Predator truly have had a moral code of not killing unarmed beings?
  When I played AVP2 as a predator I did collect a dozen heads of scientists who were unarmed. If someone would ask me why did I kill them, I'd say I dislike screaming, and I...*uh* ...like collecting heads.........

" @Yaujtapool:   Your right... Didn't in, the first movie, predator first snipe solders from afar, and when Arnold was unarmed (but fashioned lots of improvised traps) went closer for a head-to-head contact, presumably to get a trophy?   That would mean that when the opposition can fight back with proper fire power a predator relies on stealth and sniper tactics, but when the opposing resistance becomes minimal then it is a time to pick up trophies from up close, similar to the way a hunter checks his kill....   Being unarmed does not mean that you will not get killed. It means just that you will not get killed FIRST! "

Thank you RavenDark. It's good to know that I wasn't the only one who sees that and how that video doesn't make any sense.
