I don't kill anything I don't eat either. However I think sometimes some people go overboard on the way they express themselves discussing carp care. With the millions of carp that are harvested commercially or shot buy bow hunters, or thrown on the bank by misguided bass fishermen, It appears not to affect the #s of carp available to catch. I get threatened by YouTube viewers who think we are carp murderers because we stand up with them for the picture. Carp are very tough and one shouldn't feel guilty if less than 1% of all the fish you have caught some how die or are injured. If you are really concerned about carp's health you wouldn't fish them, pulling on a hook stuck in your sensitive lips has got to hurt. Do your best and enjoy the sport, and let others enjoy it their way also. Also every carp pond, river, or lake has trophy bass and other "Good" fish because they have plenty of carp roe and fingerlings to eat.
