Now that I think about it, this really is a flawed argument.

If Tilly's psychotic behavior is a result of being in captivity for decades then using his sperm is fine. He wasn't born as Killa Tilly.

On the other hand, if Sealand had to misfortune of capturing an orca that was innately psychotic, then SeaWorld is screwed. I don't think this is the case though. A lazy search only shows one reference to his offspring killing anyone. Keto is Tilly's grandson: http://www.abc.es/20101003/comunidad-canarias/orca-keto-ataco-causo-20101003.html. I would expect a whole history of violent behavior in his family tree given mow prolific of a fucker he is.
