Because of Cecil, the Lion I know that my feelings regarding this story are shared by others - 'collecting' this male specimen of the species was the wrong thing to do. He 'collected' it because it was perfectly healthy, therefore there would be others.
In the UK 'egg collectors' that collect rare birds eggs get given short shrift, actual birds in far off places aren't afford Cecil the Lion levels of outrage yet the sentiment is the same, at least for me.
