I hear the whole story of why Athena's faith in the Church of Light was broken and how she met this supposed Heretic God.
I must say that even though I was surprised by what I heard, the Church of Light let an entire city become a sacrifice just to have the opportunity to defeat an Heretic God.
I understand the logic behind it, it's always the good of the many for the sacrifice of the few, in theory, it can be understood, but there's no way to be shocked in practice, they accepted to break their own teachings and ideals in exchange for victory, they are willing anything for victory.
This worries me since this is from an enemy willing to do anything for the victory I'm talking about.
The mentality of the Church of Light is the same as that of any large organization that has been in power for a long time, they think they are above morals, and the law and that everything they do is right.
