Final answer:
Alexander's move into India was ambitious, but ultimately led to his empire's downfall. Avoiding India may have prolonged his reign, but the empire's end would likely have been unchanged.
Step-by-step explanation:
Alexander's move into India can be seen as ambitious but ultimately contributed to his empire's downfall. By pushing his troops too hard and venturing into unknown territory, Alexander faced a mutiny and eventually died soon after. If he hadn't tried to extend his empire in this way, his reign may have been prolonged, but the ultimate end of his empire would likely have remained the same.
