Nightblood and Ruin

[Lightwalker he/him]

I haven't finished all the cosmere books but I have a theory anyway. Nightblood seems very chaotic and destructive kind of like Ruin. He is also black and trails smoky stuff also like Ruin. Could they be connected somehow?

[Naight]

I dont think so

[Brightlord M. Alhstrom he/him]

Not really. You find destructive/black/smoky things in almost every story. Midnight Essence in Stormlight Archive. Skaze in Elantris. Nightblood in Warbreaker. Shades in Shadows for Silence. Many things can be evil and destructive without being of Ruin.
