Would it be possible to seal the dark of a person deep down inside them? Having them struggle with it? Maybe even when it releases, making them go mad with themselves?
*Just a question*
Psychologically? Sure. But not in the way you would think, more along the lines of repressed memories (or even wiped/erased memories if we're using the force), but not so much a conscious "I have sealed my evils deep within my psyche" kind of thing.
Regarding the actual dark side of the force? I mean, I guess. But I'm not really sure how it would play out. I've never delved into it, and I don't think many people have either, but I think it would be similar to the above in a different delivery.
But if we're talking magical sealing, like sealing something inside of a jar kind of thing, I don't think it would work that way. Not saying you couldn't have such a thing happen, just kind of far-fetched to me.
