Odin and Loki are two sides of the same coin.
You can choose the path of pain, and growth, by choosing the path of Odin.
You can have it forced upon you, without being able to have any control in the process, by choosing to remain stagnant. And by doing so, offering yourself to Loki.
Either way, there is pain. And growth. But in one you are an active participant. And in one you are the victim.
