Of course not.
No matter how bad life sucks, you can still find rewards that make it worth living.
Craig can get a college degree while in prison and write the next great American novel. Or, he can start a mock family with his cellmates and find a series of rewarding relationships as he moves into his golden years. Happiness can be found in something as trivial as that first Newport drag in the morning, or going toe-to-toe with the essays in the yard over smuggling rights.
There is always hope, bastiano.
