Eurus has been lonely since he was a child, and only Sherlock is the most similar to him. I am smart and higher than ordinary people, but my moral standards were not fully established before the age of 6-8, so I made a playmate who killed my brother, thinking that my brother would play with me.

But I didn’t expect to cause huge harm to my brother. Maybe it's the long-term confinement, or maybe it's the inability to accept the loss, the emotion is deprived, and the personality begins to split. The more painful it is, the more I want my brother to accompany me. So later he noticed moriarty's interest in his brother, so he planned everything to attract his brother to accompany him.
