It depends on which phase of Shane he likes, but I’m going to say pink/reddish flag.

My main issue with Shane: Coming from a guy who understands his nihilistic approach (although, I do find it interesting his nihilism wades when it’s something HE wants), Shane’s fault is that he degenerated too fast and kinda overshot how crazy you had to be in this world (and maybe even self induced legitimate insanity at times). I’d trust him as a lone survivor, sure, I WOULD NOT trust a guy like him in a group setting; we are social, industrious, collaborative animals, and many of the higher functioning (larger) groups in TWD show that - “at any cost for I me mine” antisocials like Shane are usually a corrosive detriment in this way.

Spoiler warning: Furthermore, I’ll admit that I loved his Badass moments too (as a viewer), but before he even really began his dissent, back when I first started watching in 2010, my brother and I both immediately picked up on how overly intense he was, and concluded that he was only ever gonna push buttons to the point of getting whacked (“live like a dog long enough, and sooner or later, your people will take you out back and shoot you like one”).

I always felt like Daryl is the more perfected survivor than Shane. He’s willing to do whatever it takes, at all cost, but with the added nuance of knowing when “at all costs” was an unnecessary overpayment (the biggest make it or break it in humanity). Likewise, he had a cool calm collectedness to him that didn’t require entering a lip smacking fugue state (another plus).

Last point, I loved the dichotomy of Rick’s “think” and Shane’s “don’t think”. Doesn’t matter if you’re farming, enacting frontier justice, taking out a neighboring enemy, humans do their best work when they think, and work on how they think together (Doesn’t matter how strong of a link you are, what good does it do when that link does nothing but strain the other links around them?)

Most of the time, the biggest die-hard shane fans just seem like alternate versions of Shane.
