We know that in the Cosmere, the method of obtaining Investiture is tied to the Intent of the Shard it comes from, although the use of the Investiture is not. For instance, Knights Radiant make oaths (Honor) that come from growth as people (Cultivation); Awakeners must be gifted Breath (Endowment); Mistborn need to survive something traumatic (Preservation); Sand Masters become more powerful through something that seems like it could be Autonomous.
How does Odium's form of magic, Voidbinding, tie into his Intent? Presumably it must be obtained through hatred in some sense, but we haven't really seen many Voidbinders. The one human one we know of seems to get it by having a corrupted spren. But perhaps we can conclude something from the Fused or Unmade, or statements made interviews.
