Perhaps the solution is to make it so that your being in the alternate reality has no bearing on the "you" of the reality you're in. So that regardless of whether you are alive or dead in this new reality, it doesn't affect your personal perception of yourself. That's not to say that that Warehouse wouldn't be shocked if a dead agent came through the Stargate and question you, but at the same time it prevents the artifact from being too powerful.

Another possible cap is to avoid interaction entirely with the "you" of the new reality. I recall reading in Gravity Falls: Journal 3 that Ford encountered a parallel universe almost exactly like his except for one key difference of events, and one of the people he talked to said you can't interact with a parallel you, or the ripple created can destroy both people (or maybe it was the whole dimension? Either way).
