Fair enough.
I think your argument about the possibility of an animal ending up unwanted and therefore is better off dead is completely illogical, though. And given all you've said so far, my impression is not of someone truly trying to figure out what is best for the animals or for the "industry"...but someone trying to justify his own lazy choices in dealing with extra babies.
If you feel that strongly that death is preferable to a chance at life as a pet in someone's home, then maybe you shouldn't be producing any at all? ALL the animals you produce and allow out of your own personal sphere of responsibility are now at risk for being neglected, abused, and abandoned. How "pretty" you judge one animal to be over another has very little to do with those chances. People spend lots of money on expensive toys all the time and then neglect and abandon them when they get bored with them. Why should your "pretty" snakes be any different? Why should they not just get put down for no other reason than that they were born at your direction???
