Ehhhh
It is different from Honor, and it is different from Odium - but remember, as stated in light merging in RoW, both tones change before they meld together.
Yes, it isn't sweeping plans like what we saw from Taravangian, but that makes sense - like even Ati (stated by Hoid to be the best of the Vessels) was corrupted by Ruin, except this is the power of the intent of two Shards, not just one.
Retribution - it's definition is semantic. But I think pettiness is extremely fitting for a Shard. As Dalinar saw in Honor, they are children. Oppression has no sense of Honor, Enmity is almost (not really, though) a synonym of Odium, Contempt is the same, Pride/Hubris is a good candidate, but it doesn't have as much of a factor of Odium, Storm is too close to the Stormfather.
