I wouldn't say "happy" as such, prepared to deal with is probably the more appropriate term. Also saying that's what they'd do when questioned about it in passing, and actually doing so are two very different things. If someone is so unhinged to actually behave in such a manner over an accident (of their own making), then they almost certainly need psychiatric help.
As per the OP I'd be absolutely gutted, and be more than willing to do the right thing and help out with vet bills/funeral costs etc., but ultimately, if I've taken all reasonable measures to prevent it from occurring (tall fences, checking the garden before letting the dog out etc.), and their inability to look after their pet has resulted in injuries or death, then I've done nothing wrong, either legally or morally. If they don't want to be reasonable about it, and accept that sometimes unfortunate accidents happen, then that says far more about them than me.
I agree, and I'm certainly not advocating that is an appropriate response, but... People hurt other people for a lot less and it happens every day.
Pets are exactly the kind of thing that provoke completely irrational and extreme responses from people who "almost certainly need psychiatric help", but in most ways seem perfectly normal. For a lot of people, they're like surrogate kids.
