If that helps them to defeat Fairy Tail in their emperor's name, yes they won't mind. But it doesn't mean that Irene should have gave them the heads up before enchanting them into Berserkers at least.

Tell the entire army that she will give them a "little extra boost" on them with that remark. To boost morale for the troops to willingly accept it and not suddenly shove it down on their throats out of nowhere.

You know, I wonder if Berserker enchantment can affect humans, can it affect Machias in sort of way? I mean sure Wahl is the only one around in the arc but if there were (implied) more like him among the 1 million army, will they be turned into Berserkers too?

Machia Berserkers... Hmm.... Uhhh... On second thought, bad idea. It screams hellspawn of Ghost Rider and Terminators.
