According to my sketchy understanding of Tibetan Buddhism, the asuras aren't evil and the devas aren't good, they've just been reborn in different realms that both aren't very conducive to ultimate liberation (the world of humans is considered optimum). Devas, the gods, don't have any capacity to reflect on the dharma because they're constantly blissed out, asuras have no time for it either because they're pathologically jealous of the gods and are forever engaged in futile attempts to conquer the world of the gods, clambering over each other to get on top, jealous of other's attainments, conceited about their own, eternally jockeying for position, with never a moment's rest or leisure, totally caught up on a world of extreme cut-throat competition. Hence both the devas and asuras are considered flawed - as are humans but we at least have a better chance of snapping out of all that passion-driven bullshit.
There is this unfortunate Western tendency to borrow teachings from other traditions and reinterpret them according to our obsession with polarities. Yes, the asuras and devas are fighting each other (if you can call it fighting, the devas are infinitely more powerful) but they're both deluded victims of their basic dispositions, as are all other sentient beings in the Six Realms. Have asuras something in common the LHP? Yes, the obstinate striving perhaps, the desperate will to get ahead at all costs maybe, but at the price of genuine self-awareness; with asuras, it's instinctual, they can't help being excessively ambitious megalomanics. Asuras aren't an advantageous spiritual role model to follow, IMHO, unless you want to become an irascible fanatic.
Can such a reinterpration of religious history succeed? It seems to have worked (for some) with Satan, the Sitra Achra, the qliphot, etc. but I must say I'm not a fan. All those concepts come with their own gargantuan historical baggage that it's hard to see why a miniscule group on the outer edge of the occult fringe should stand a chance in turning them into something they never were. So ok, write a book about the heroic struggle of the asuras who are the good guys, ack-shu-ally, although nobody said they were evil to begin with - in this case, edgelordy inversion doesn't work, and the LHP isn't 'evil' anway, so why bother?
