in addition, story would have actually been soooo much better if the explanation of him causing world destruction was an actual direct cause of world destruction, such as his attempts at breaking the natural order of things set by god, interference by reincarnators and his second chance life is blowing holes in the the universe, and his very existence and all that he does is making the holes larger, ultimately leading to a extinction event where world gets restart. but instead we get a bs excuse with the simple solution of 'just be stronger than original hero --> take place -->all good'
Except none of those make sense. He literally received his skills from god.

such as, doesn't have to be that exactly, just an example to how it doesn't have to go through the whole played out typicalness of this kinds of reincarnation/time travel story
that typical shounen "I WILL CHANGE EVERYTHING AND MAKE HAPPY HAPPY TIME FOR EVERYONE!!" bs, i freakin cringed when the mc went "i'll be way stronger" followed by that demonic eye to demonstrate his inhuman will, ugh.
