Blessing? More like a curse.
This "blessing" shit in this world... is more of a fucking curse.
Everything else we saw from it showed how fucked up things could get, but if some of the "spoilers" I saw in clips from the anime will happen here... shit gets worse.
No one here is gonna disagree with you guys. These blessings pretty much are curses.
The following is just me guessing at things, so take it with a grain of salt. (And not the salt of other's tears.

)
The real question is: who
really made things the way they are? If it's the actual creator-god of this world, then they got one helluva fucked up personality. (And it's time to go all Kratos on their ass.)
Alternatively, it could be an evil god who snuck in and fucked with the system. Why? What better way of throwing things so off-kilter that you can establish yourself without too much resistance from the other god?
