What I'm saying is the series basically started like that, and evolved. Each game is different gameplay wise and story wise. I think it's unfair to judge the entire series on technically the 3rd (mgs1) and 4th (mgs2) games in the series. Especially when the 3rd is considered to be the best by the majority.
Almost every character in the series isn't really good or bad, but I don't think PW or TPP contradicts his character in anyway, and by the end of TPP I definitely felt like I got a glimpse of the twisted character we see in MG2.
Glimpse of the secret good guy. He used someone... who gives a ****, which is a far cry from any true villain of the series.
