Ethical Question for Jurassic park
 

I know this is a question of Ethical standards. But if Humans could create Dino DNA should we create these creatures? As it is humanity has bred back (or are trying to) the Quagga Zebra, Aurochs Cow, and even the Wholly Mammoth.

My personal feeling is we know too little of these creatures to properly support them in the Ecosystem. Plus in 65 million years earth has changed a lot.

Also give a legit answer. Do not just say "yes" or "no". All reasons will be respected.
