re: Who was the most evil individual in Breaking Bad?

You raise a good point and I can certainly see both sides. For me though, all of Hector's other actions combined with his creation of the cousins just puts him over the top. Who knows how they would have turned out without exposure to him. I may be wrong here, but didn't he also raise Tuco (not sure, but I think it was alluded to at some point)? His sole act of redemption at the end just couldn't make up for all of that to me.
