I feel this is an important point to make, and the main reason i brought up that this type of thing is accross the whole pet industry and not just in the reptile hobby.
At the end of the day, you can choose to support a person or not, and Wymans point of dont make assumptions holds true with this. If you want to make an assumption about a person, nobody here can stop you. It can have logic leading to it, but unless you know for sure, it should be used to form your own opinion, and guide you to ask questions for clarification. I think the place some users are getting upset on the other side here is how he is being treated as guilty unless proven innocent.
I get the reasoning behind thinking he euthanized the animals in some way shape or form, but it is an important reminder that none of us should be demonizing a person without 100% assurance they have done the act, and even then, intent matters. If he did do it, we still dont know his reasoning, and doing testing to ensure it is safe to breed and getting a sufficiently large data pool to know so before allowing them out into the hobbt may cost 50-100 lives, but if an issue was found may save thousands of lives if everyone started breeding them once out of his control.
So my opinion i feel comfortable stating is under the following circumstance, i would not be comfortable dealing with this person, and would personally feel they acted in an unethical manner. If any one of these factors is missing, then i would not see a problem:
All animals produced were perfectly healthy with no defects.
All animals taken out of the project were killed instead of rehomed or sold.
The sole purpose of putting the animals down was to protect a financial interest or personal claim to fame.
Because of the uncertainty, there are many things that may be the case that cannot be ignored. The animals may be alive, if they are dead, he may have protecting the many by killing the few to ensure no genetic issues before allowing it to be released.
At the end of the day, while a reply for him would help clear much of this up, i can see why one would be afraid to respond even if they did nothing wrong.
I acknowledge and recognize if this person does meet the above criteria, they wont be the first or last, and i have likely dealt with the products of such behavior in the past, but this is something I already addressed in my previous posts, and something Wyman covered quiet clearly in his, so i wont beat a dead horse on that front.
