Griffith is a hardcore metrosexual. A deep apostle voice wouldnt work for him at all. His english voice was perfect. I can see why one would initially think of him as having an apostle voice.. if youre going by the manga.. because you see Femto before you see Griffith.. and Femto is a Godhand. But Griffith was Griffith before he was Femto... and while he could kick just about anyones ass.. a big, tough manly-man, Griffith was not. The semi-feminine, confident, ambitious, articulate, sophisticated, well mannered, and extremely passionate voice worked very well with him.
