there's not one player here that wont kill, maim or harm another player who is at a vulnerable position. be it landing or with less skill. it's a joke to think otherwise.
nishida please name one player that only fights others of equal skill 
.
I'm sorry to disappoint if you think you laid an especially clever trap. I dismissed your minor point since the main thrust of the discussion was about chivalry, your upper statement which is of the 'for all' form is incorrect, I have encountered several players who value courtesy above adding another notch to their (let's face it, largely meaningless) Aces High scorecard.
To answer your lesser point: what is less ignoble, to spend years of learning, practising and developing skill then applying that whatever fight unfolds (often initially unfair fights, outnumbered, out energied etc), or to swoop through field ack at 450 m.p.h to blast an aircraft on approach or one which hasn't got its wheels yet off the ground?
