I valued what Zeref said because a lot of people especially in Sabertooth acting like Hades, they felt superior because of their powers, the strongest five who changed Sabertooth, yeah, but the five were defeated, because they didn't know their place.

Mashima explained it in this arc : nobody is superior to others, nobody is allowed to walk on God's domain ( like in Full metal Alchemist with the human transmutation ) especially with Time ( Ultear, Eclipse ), strenght isn't the only thing to value : friends and intelligence are important too, past is the past and can't be rewritten.

Mashima also shown that Dragons are not something that can be taken lightly, and if humans want to defeat Acnologia, they had to work hard.

One last thing, don't forget Mashima is Japanese, and his way of thinking is different than the western one.
