I like to balance the line. My current character actually maintains a Tainted state, looking for ways to purge corruption when he feels he's nearing a threshold. I mean not all corrupted characters actively seek to corrupt. Aileh is an example. Don't always have to be white and black in these things. Anything that would obviously corrupt I'd pass on, like pushing Azzy/Liaden into the pool. Or whenever they add demonization for Brienne, Cait, etc. Viv made sense to corrupt because the Champion didn't intend to do it, so as a play I let it happen. I keep demons in my Wayfort, they aren't inherently evil and can be reasoned with.
