Just ignore them. They feel the need to express themselves in the face of criticism, and they're more than at liberty to do so, but it's just a waste of energy engaging with it at this point. Let them say their piece and move on.
Perfectly valid interpretation and reaction, really. It's an odd thing to say, and I'm being pretty generous in light of how much they tried to hammer home what a good guy he was at heart in Elpis. He does call himself a megalomaniacal madman, and the story more or less admits he has infiltrated, raised up and crushed what we can only assume to be countless civilisations - Allag and Garlemald simply being the mightiest - which there's something a little more... sinister about than the other, more simplistic wanton destructive methods employed by the Ascians. Honestly, I don't know if I actually agree with the game's implied message that any good-hearted person would be driven to such acts by what he went through, but none of us could even imagine the reality of living that long, so who knows?
Oh, absolutely, with all the subtlety of a brick through the window, but I still find it interesting to dissect the meaning behind... and what they were hoping to gain from it.
