If you don't think they are predators by nature, you are being delusional.
wreck havoc on the local populations that haven't evolved to defend/hide/outsmart/outwit/survive this predator.
If you actually believe in your arguments, then I suppose you agree we should exterminate Humans? - I'm not making a point by asking a question, but the word Cat and Human are interchangeable in your posts and in fact I believe worse with Humans.
Edit: Also one can argue since Humans are a part of Evolution then Cats being brought into the ecosystem by us is also a causation of that very system.
Edit 2: Grammar.
