Ummm...
Not sure you answered my question in that incoherent mess there breh.
You said Shane would have thrown his own baby in the trash to save his own ass and then I countered with the fact that he was selfless when he offered to get supplies for Carl when nobody else would go and when he gave the chance for Otis to take the supplies and run.
If Shane was completely morally bankrupt as you say, Shane wouldn't even have offered to go on the supply run for Carl, and he wouldn't have offered Otis to take the supplies and run without him.
Nobody is denying Shane was unhinged later on but Shane was fine before Rick came.
We're talking about a guy who barricaded the door to his best friend's hospital room so the Walkers couldn't get him. If Shane was a snake and never cared. Rick wouldn't have even be alive to make his comeback, breh.
