Why is Teen Wolf's Scott McCall hated by fans for his mistakes?

I've been thinking of rewatching Teen Wolf, it's one of my favorite shows. It may not have been perfect nor had a big budget but the show had an interesting supernatural story to tell. Something, I noticed within this fandom is that Scott McCall, the titular teen wolf, is unfairly hated. Yes, he's made some bad mistakes and decisions throughout the series but so have all the other heroic characters.

I don't know why his mistakes are held against him, while many fans seem to gloss over the other characters' mistakes. Scott was a teenager when he was bitten by a werewolf and had quickly found himself in the supernatural world. Since this new experience as a werewolf (as well as the supernatural) didn't include an instruction manual, Scott and his friends/pack mates were sort of making it up as they went along. They might have gotten some help every now and then but ultimately it was up to them to figure out what to do and lot of times included making bad decisions and a lot of mistakes.

I know as the leader of his small yet ever growing pack, Scott was supposed to know what to do but truly none of them knew what they were doing. Which is why I don't understand why so many fans put so much fault on Scott when he was just as clueless as the rest of his friends in dealing with the supernatural.
