This kind of immature action that utilized three infinity stones, and executed a multiverse level ritual could actually be a really good lesson if Harry faces consequences from this. How long has he been alive for and how many step backs or failures has he failed to overcome?? His been alive for a long time and faced almost zero step backs. This should turn into a sticking point were Harry gets humbled by something or someone and learns this sort of behavior no matter how good feeling is a immature and improper use of the power he wields. I get the morality and ethics are stupid concepts when spoken about a being that can bend reality to their whim. But still this one off filler chapter could actually be a really great opportunity to explore how Harry actually reacts to implicitly doing something stupid and growing from it.
