Evil shows, their goal is to catch prey, play with it in their claws, make it go out and support them for long enough to raise their cubs.
They will spend twenty years torturing their prey, driving him to a heart attack at 43, having spawned, sent forth their cubs to hunt on their own, they will self indulge on the life insurance.
