Elijah Mikaelson had always put his brother first. He did it when they were children and he did it when they were immortal. Nothing was more important than the oath 'always and forever' and that included love. It didn't matter how much that person meant to him, Niklaus would always come first - the guilt just drew him in. This was the same case when it came to leaving Rosemary Evans. He didn't know she was pregnant nor did he know just how much that child would mean to him as soon as he found out. She was the exception to 'always and forever' with Niklaus not that the hybrid knew it... well until they were all dragged there by magic to watch the life of that child and her cousin.
