I'm rewatching TWD right now and I can't stop thinking about how Shane is likely what Joel was like in the years that we don't see him. The twenty years between Sarah's death and when the story picks back up in Boston.
How Shane has a hyper focus on keeping Lori and Carl alive and how nothing and no one else matters and how that was likely the same for Joel, except his focus was probably on Tommy and maybe whoever else made it into their group for the time being.
And I think it's easier to "forgive" Joel because we have no counterpart like Rick in the series. We don't see Tommy arguing with Joel over what's right and what's wrong, if there even was any arguing to begin with. I imagine Tommy gave Joel a LOT of freeway and chalking things up to grief and the general chaos of the world as they knew it ending in real time.
Anyway, I just think there are probably many parallels between Shane and Joel and their ruthlesness when it comes to protecting what they hold most dear to their heart.
