Hello. Nice to meet you.
I've learned you cannot avoid lessons that are to be taught to you, they are inevitable. He would have definitely been given the sign if he saw properly he may or may not have saw he was in grave danger in divination assuming he did the method appropriately and efficiently. Even if somehow he defied the grid or script of reality it would just surface again equally as it was supposed to be earlier. I would know from experience.
Assuming also if he had sufficent enough of circumstance, energy, karma and countless other cosmic factors he might have reversed the lesson into something less traumatic at least unto himself. It would be possible if it was put off it may have an equal lesson somewhere down the line in his soul cycles and life times or be lived via quantum reality. According to the later, he would have had every possible outcome at that point and thus learnd, did not, avoided it all together.
However I can say it would be more relative to his own view point and all his other selves emotional mental, spiritual what not on the scenario. As there are infinite amount of outcomes and variables even if there are only two paths to take.
For future reference, it is often polite to say "Hi" before asking a question
hope this helped you.
