Instead of doing something like finding a proper place to regroup, and consolidate enough strength to fight back first, he's willing to jump into the fray in such a state.
This guy just feels like an idiot making one bad decision after another. What's his plan to face the evil witch who has betrayed and killed 5 other saints and stole their power and has an entire army behind her back?
His own power is unstable, the only other saint has no guts and lets everyone walk all over her, and most of his own original group is splintered and reduced to near nothing. And the other remaining church factions are filled with people who are shady or proud and arrogant garbage.
