I think it's less that and more that Time Lapse is being reckless in his alterations of the universes. If he keeps up the behavior, he may end up as the pony version of John "Jigsaw" Kramer, becoming the very thing he was trying to eliminate.

Well you’re half right. Alter Paths spell is like a drug if used and administered correctly in the right dose it’ll be fine. But Timelapse is abusing this. If you read the part about black veins it’s a sign.

Old man consequences?
