"Never use emotional Allomancy on an obligator. They're all trained to recognize when their passions are being manipulated." Mistborn the final empire, chapter 3, emphasis added.
I find it a little suspicious that "passions" was used here instead of "emotions." Like it could be a hint at a future conflict against a god of passion, maybe.
Marsh could be Scadrial's first (or last?) line of defense in Cosmere Wars. This is the guy who kept his identity and will even under the direct influence of Ruin. He'll know when his feelings are being touched again. Maybe he could even train others to recognize the touch and resist it.
Help us, Marsh, you're our only hope.
