Okay, I obviously don't know where this story is headed, just like everyone else, so bear with me.
However, if it is headed in a direction that might eventually let Retribution and Harmony face off, then I believe that Kelsier is right to be scared of Harmony not being decisive enough to act against Retribution. Even if you don't believe this to be the future of the cosmere, what do you think would happen if this hypothetically happened?
The stark difference between Retribution's drive to act and plan and scheme, and Harmony's indecisive contentment is dangerous for the Cosmere. As the only other dishardic entity in the Cosmere, he needs to branch out and find ways to let his shards work together. I think Harmony would get splintered by Retribution if they were to face off as the Cosmere currently stands. What do you all think?
follow-up question, Which shard or potential combination of shards is best poised to stop Retribution?
follow-up to that follow-up, do you think Retribution would ever also take up the shard of Cultivation, becoming the first trishardic being?
Thanks for coming to my ted talk.
