No no no you silly goose!
You're all standing on the elevator balcony in this picture!
Just throw him down off the balcony. No need to throw him out the window. Talk about unnecessary violence, I mean gosh, what kind of psychotic lunatic are you? Geeze.
In any case: I am now taking bets on how many times Poe needs to whack Sabin with
this in order to kill him. Seeing as Sabin will have been tossed over a modestly high balcony he may or may not be temporarily disoriented, Poe will not particularly prioritize aiming for his head but will not make a point of avoiding it. Assume each whack is equivalent to a 'grand slam' VATS attack on an unaware opponent.
