No, he's a poor man locked into a ravenous addiction. He no longer even truly enjoys the cookies, merely the sensation they bring, the ghost of that first bite.
Look at how he reacts, the nigh berserker focus on the consumption, or at least destruction, of any cookie brought into his presence.
It is not Cookie who is the monster, but those who have kept feeding his broken will, bringing him ever more. Look what they do! Parade him out, knowing a plateful lays in wait! Planted for their amusement! And he knows, but what other choice is there left? They've taken everything. Everything but the sweet sweet cookies.
I once read that in his original iteration Cookie Monster did have a hole in his mouth so he could actually consume the cookies but children found it too disturbing so they modified it so he just sprays them everywhere.
