People who complain bitterly about the unfairness of it all when unfortunate consequences to their actions are guaranteed.
Warning: pet death
My BIL is ranting all over FB (seriously, multiple posts a day) about how he hates God and God is unfair because his cat, which he allowed to play unsupervised in a rural area known to be heavily populated with coyotes, hawks, owls, rattlesnakes, etc, was killed by one of these predators. They've lost uncounted numbers of semi-feral cats and kittens over the years to the local fauna with nary a twitch on his part, but because he had bonded somehow with this last cat, it is the most unjust thing to ever happen. Well, it was, actually - to the cat, who wasn't protected by the people she trusted.
