When Nightmare got split from Corrupt he was very confused. The last thing nightmare remembered was almost dying and hearing his mother's dying screams as the villagers cut her down to get to the apples.

He remembers staring at the apple and just wanting to live. Wanting to not die. Wanting to be safe again. He grbabed the golden apple, watched it corrupt by his own negative feelings. And bit down anyway.

Only to wake up on battlefield. His body feeling weird and almost as if there is a disconnect. No where near anywhere he recognized and with all these weird skeletons around him. Especially the goop guy who reminds him of the corrupted apple a bit.

Nightmare does not, and never will, remember his time when he was in Corrupt. He was asleep and feeling slowly. All that he remembers are some nonsense dreams or beginning nightmares that always ended with a darkness that fell over him like a blanket. (He was able to find this comparison later when he finally got his first bed. He realises that while he was asleep he just felt wrapped up and cocooned.)

Corrupt for a ling time believed all of nightmares memories to be his own. Same for his feelings. But always felt weird about being called Nightmare.

Dream even said as much that he was not his brother anymore. So Corrupt agreed and decided to be named corrupt. As a way to reclaim the insult the villagers and later dream would throw at him. (Well the villagers at nightmare but you get the deal)

The reason why corrupt wasnt completely evil and more of a lawful neutral? It was because the negative feelings that corrupted the golden apple were fear and desperation. And mot for revenge or anything. Nightmare had wanted above else to feel safe.

And the apples are all about emotions. So when corrupt first formed the thing he had foremost was a wish to be safe and not be hurt anymore. The rage and hatred came later when within seconds all the memories of what the villagers said and did came rushing back.

When they split and when corrupt managed to see the difference between them and who was who he understands that in a way nightmare's honest and well positive wish to just feel safe was the thing that made corrupt more than just a negative creature band on destroying everything. (The thin dream says he is)
