I don't think that picture would exist if it had nothing to do with the game. I wouldn't worry about it because a fictional game has no baring on how angels are portrayed in Judaism and Christianity. I adhere to beliefs within Judaism and DmC's portray of angels doesn't bother me in the least because its fiction. So don't worry.
I'm not really worried, I'm used to games portraying angels as evil, villainous, etc.. I think it's because I'm not used to angels being portrayed as seducers. But I'll get used to it.
Now on the topic of Eva, there's one reason why I don't believe that Eva will be anything bad.
You guys remember the glowing mark on Dante's back? Obviously it's angelic, but its sword- like shape makes me think that that's Rebellion in a sealed form. Considering the assumption that it's an angelic sealing, I think Eva might have sealed it so that Dante won't have to carry it around in public.
