The animal kingdom is luigifying too! πͺ
Maybe get some kind of confirmation a person is a shitty person before celebrating their death? All I can find about this guy is that he was prominent in wildlife conservation activism. Do you have sources I didn't read?
Alternatively, I guess you might try and make the argument that he must have been a shitty person solely because he started, ran, and/or sold a business at some point in his life. I wouldn't recommend it, as that's a shitty argument on its own merits, but you could try.
