The main theme of The Walking Dead franchise is hope in the face of futility. It is not fatalism. It is not "everything sucks and it's not worth living anymore". It means that no matter how awful it gets, no matter how many times you find your daughters decapitated in a prison barber shop, or see your husband beaten to death with a baseball bat, you keep going.
Kenny says as much in Episode 5... two minutes before killing himself in a stupid and contrived gesture where he had plenty of time to escape. This is why The Walking Dead by Telltale Games is a failure. It talks the talk, but it does not walk the walk.
Fortunately, I have gone to great lengths to fix the ending of TWD. Please, hold your applause:
