In Fire Emblem If, we will have to choose an adventure. Now, this question is specifically asking: "Who would you side with?" NOT: "Who is morally in the right?"
This is what I mean:
Choosing Nohr would not be choosing evil, you are choosing the dangerous mission of turning your friends against their evil leader, Garon. This will be more challenging, and you would never know who might stab you in the back. Nohr's leadership is obviously in the wrong. The way i look at it, Garon is the real villain, not your surrogate family that loves and cares about you. This choice is less about good over evil and more about which people don't deserve to be betrayed.
Personally, i am most looking forward to the third path that doesn't make you pick a side. But, i think blood is not as strong as bond. Choosing Hoshido would be honorable, in the context of the war over-all. At the same time, i don't want to give up on the people being manipulated by evil. I would choose to save them, and use their strength to help me overthrow the king of darkness.
What do you think? This is most assuredly the most important decision in the game, since it sets you down a path very different from the other. Who will you choose? Are you influenced by logic or emotion? Are you bound by Blood... or Loyalty? Neither choice is wrong... but we have to choose.
