While they were on the topic of Ragnarok, Arnold wanted to know why didn't Odin do something about it? If the children of Loki were the ones to cause the most problems, they should have just made him... sterile. That right there would have solved the problem itself, or they could just keep killing him as he resurrected again and again.
"The answer to that question is pretty straightforward." Heimdall mumbled, "Even among the gods, we can not kill other of our kind just because of a prophecy. You see, in the billions of years we have existed, there had been innumerable prophecies made. Most of them were false."
"As a result, we can not act upon mere prophecies alone." Thor chimed in, "If we did, the gods would be in a constant war with each other and mortals as well. Thus a rule was made by the immortal one that no god will act upon these prophecies."
