The whole Vali thing is really ironic. He is the polar opposite of Isse. All the latent demonic talent in the world, the scion of one of the most if not the most important devil bloodlines.

And yet even with all of that his life is sad and pathetic in comparison to all the things Issei in life which is love and family.
