Scott Disick should have his legs sliced open, blood gushing, and then be fed to the gators ... that's what a Reptile Rescue Org wants ... after Scott shot an alligator in the face on a recent episode of "Kourtney and Kim Take Miami."
Mary Hart from International Reptile Rescue -- a world renowned nonprofit that's been rescuing reptiles for decades -- tells TMZ, Scott's hunting trip which aired this weekend on E! was a cruel, insensitive act.
She says, "He didn’t kill that alligator, he murdered that alligator." And she goes on: "Fairness would be to cut both his thighs so he bleeds and then toss him in a gator pond with gators small enough to rip him apart slowly and painfully."
FYI ... in the episode Scott hunted the gator (legally) in Florida ... shot at point-blank range in the head and later skinned and gutted it -- all while cameras rolled.
PETA, Tori Spelling, Shannon Elizabeth, and a slew of celebs have already slammed Scott and E! for the gator-cide ... calling it upsetting, horrible, pathetic and f****d up.
E! and Scott have yet to respond.
