The greatest Warrior Achilles?

ok take this seriously because Achilles was alexander the great's hero also, as he is mine. i just am wondering what you people think on here that like should i have him my hero even though he was a demi-god its just weird i think that i want to have him my hero and everything but he wasa demi god and i would never relate you see where i am going? i am not a god or demi god obviously and could never match up to him as a man or god w/e so should i even have him as my hero?? like trying to relate hero to give me strength when if go into combat? I join the army in 6 months with an option 40. dont be stupid this is serious
