Tainted Snow
Edward looked up at the cloud covered sky as snow continued to fall onto Central City. He couldn't help but notice how much the snow resembled sin as he stood upon the stairs of Central Headquarters.
You may think, how could someone come up with such a ludicrous thought? How could pure, white snow resemble vile sin? Edward spread out his bare hands and let the snow fall upon them. He looked down at them as he watched the snowflakes dissolve on his flesh hand, yet remained the same on his metallic one.
They were the same, snow and sin. Sin was cold like snow, sin slowly makes you numb the longer you are exposed to it. The bitter, sharp coldness of sin cuts off your circulation of life, and soon you can no longer feel anything. Just like snow. Sin lures you in with temptation, with its innocent appearance of pure white, and you want to stay. Only when you can no longer feel your limbs, do you realize it's too late. Too late to be saved, and too late to be forgiven.
Edward was like snow. He knew the temptation of sin. He remembered the numbness of his limbs in the freezing darkness of the gate. He was too late to be saved. And too late to be forgiven. The power alchemy had promised, the confidence that he could do something no one else could, the need to see your mother's face again, was the innocent purity of the sin that was blasphemy.
Every time it rained or snowed, he could feel that numbness, the reminder of his selfishness, and he would keep sinning until he reached his goal. His blood-stained hands tainting the snow.
