I think Merlin was BAMF on the pixie because he didn't think of her as an actual person. He just knew she was a pixie, thats the same reason he doesn't hesitate to zap the sidhe either, he doesn't connect with them or know them personally to really care like he does about Morgana. Morgana and he were good friends in the beginning, up until the witch's quickening, so he has a special soft spot for her. Again, the zapping of the pixie was not meant to be heartfelt or conflicting, it was another magical creature wanting to destroy Albion's time, (despite the lightness and humor of the episode) like Catrina, Sigan, the griffin, wraiths, etc etc. The audience was not meant to connect with Grunhilda either, we are set to belive the sidhe are bad news for camelot, and merlin knows that too, and that is all he needs to know to start going lightning on those guys.
