There are only a very few carnivores today that will eat only something they have killed (like snakes) and all of them are cold-blooded and don't need a steady supply of food.
As for T. rex and endothermia, it's possible that Rex started as fully endothermic when young, then became only partially endothermic as it got bigger, since its size would allow it to retain heat much better than a smaller animal. Then it wouldn't need a s much food as a fully endothermic beast its size would need.
Another of Horner's reasons as to why T. rex was a scavenger was its jaw power and teeth shape. Thick armor-piecing spikes backed up by jaws that could exert several tons per square inch, excellent for penetrating thick skins and armored hides as well as crunching up bones to get the tasty marrow. Horner says "Since T. rex was a bone-crushing animal, he was a scavenger, because only scavengers need to break the bones to get what the predators can't get to after they have taken all of the meat." For this, I have to point out hyenas, who have the strongest bite force of any mammal, hell any land animal, regularly chomp up bones like the candy sticks that come with Lik-M-Aid, and are very successful predators, more so than lions.
