Nah, Kojima has stated in interviews the dialogue in the early Metal gear games were heavily influenced by late 80's early 90's action movies. It's supposed to be over the top and bombastic.With worse writing (I mean, come the fuck on, you have an explosives expert actually say things like "killed my soul with bombs" and "defuse my sins"?)
I honestly think that's why the Quiet caused such a meltdown among sjw fags. If Quiet had been introduced in the 90's no one would have cared. The culture changed radically between the early 2000's and the 2010's.
