What if the people who killed this Gator, was some hungry homeless people who live in the woods?

So that'd be a choice between mugging an unarmed human and breaking into private property, ignoring the opportunity for burglary and taking a knife to the limbs of a Massive Fuck-Off alligator? Yeaaaaah the metaphorical starving homeless people would take the free n' easy alligator meat every. Single. Time.

try to think of all the possibilities of how that gator ,made other animals meet their demise.

It sneaked up on them, tapped them on the shoulder and said "Demise, this is Animal. Animal, meet Demise." with the soothing tone of Stephen Fry?
