It didn't seem like Momoshiki did that out of spite.. it seemed like he peered into Boruto's future and realized that Boruto is special, BUT he would need that power in order to succeed at whatever he is destined to succeed at?? Perhaps. It might not be purely altruistic, though. It might be that he simply wants to continue his own legacy by perpetuating his chakra, or perhaps it will allow him to exert his will over Boruto somehow. Maybe it will make it possible for him to be reborn. Maybe it will even be a beacon that draws more Otsutski to the world.

While I personally think it'll probably just be a power source similar to a Curse Seal, there are certainly lots of other possibilities.
