Arvo? Or a better question, is there anyone out there who likes all of the characters to some degree?
I have an inability to hate most of the characters in this game even when they do shitty things. Carver is the only exception. (And there's also my weird dislike of Becca but that's...I don't even know what that's about to be honest.) Hell, I even like Troy but never Carver. Even though Arvo has done the worst possible thing in the eyes of a majority of the players (Clementine is practically a daughter to many people so the outrage is understandable.) I still can't hate him. I know shooting someone the way he did regardless of if he wanted revenge or was scared or whatever his reasoning was is inexcusable but for some reason it doesn't matter to me I still like him.
He reminds me a lot of Lilly, maybe that's part of the reason. In my first two plays of the game I left her at the side of the road without a second thought but thinking back on it, I regret doing that and I forgive her even though unlike Arvo she actually managed to kill the person she shot. I just miss Lilly and I like to point out the parallels between her and Arvo. (Right down to watching them both panic and try to give CPR to the person they tried to save...) I think the whole point of the dream-sequence after Clementine gets shot is to show that their situations were similar. They both thought that someone had murdered their family member. (Lilly especially considering there seemed to be a possibility of reviving Larry.) Lilly grew increasingly paranoid with the thievery and it also probably made her very angry inside to have to live and work with the people whom she saw as the murderer(s) of her father. Arvo's breakdown was driven by Kenny's abuse and his festering hatred of the person he believed to have been the killer of his sister.
Also, I don't think Arvo being 'Ben 2.0' is particularly accurate, I can't remember too much from the first season but while Ben's screw ups were colossal he stole to keep the bandits away and it just massively backfired on him. I thought Ben's intentions were generally good, I can't remember a time where Ben's actions could be interpreted as being done out of paranoia or revenge so I don't agree with a lot of the comparisons of Arvo to Ben.
I'm sorta getting off topic but what I'm trying to say here is that there are pretty much no characters that I actually truly hate and want to kill in this game. Arvo, Lilly, Jane, Bonnie, Mike etc. etc. and all the other characters that people are wishing get burned at the stake, I actually fucking like. A lot.
