Devouring Pellin's child seemed like he was taking it too far and crossing a line that should not be crossed. However, Simon's mind was made up and the waves that formed in his heart after killing the boy was no more.
There were several reasons why Simon chose to devour Pellin's son, and one of them was because he couldn't leave any trace behind.
Simon was not certain what methods the Shadowgrave Clan had to investigate the causes of the death of a clan member, but he knew of some methods demons usually used.
Devour could counter these methods because it consumed nearly everything a demon had.
To prevent the clan from figuring out that he was the one that killed Pellin's son, he had to do some things, and devouring the child was one of them.
Pellin's child had not even awakened his demon heart and birthed his chaos flame, so he gained very little from devouring the child.
Only a drop of ink that further stained the whiteness of his past life's hero heart.
