It is, sadly. They killed over 40. It's very sad, and the fact that the father suffered
"snake related post traumatic stress disorder" is also depressing. A normal person should not react that way to being around snakes, even if your house is full of them. All it takes it a little time to sit down and think "Ok, are these snakes really a danger to me? Do I have to kill or hurt them or can I be compassionate? Perhaps I should learn more about them before jumping to conclusions." In essence, if the man had used logical thinking and common sense he wouldn't be having emotional issues right now.
I feel very badly for the snakes and I hope things work out for everyone involved. Persoanlly, because of my small animals, I'd board everything that could be eaten someplace, call in wildlife control and be done with it. Relocate them someplace else as opposed to killing them.
