In the past-life memories William accessed, it was only during his escape from the Orphanage at age ten that he was forced to kill some of the security personnel,
In fact, it wasn't his first time killing; otherwise, he wouldn't have been able to so seamlessly dispatch several well-trained adults, and after claiming several lives on his first occasion, he appeared calm and composed, this in no way affected his escape plan.
The real "murder memories" were sealed and stored in the deeper layers of Yi Chen's memory vault,
They were contained specifically because these memories could have a detrimental effect on the individual, potentially causing a severe deterioration in 'William's' personality.
However, Yi Chen felt that now was the right time to release these memories,
since the theme of the memories was directly related to the 'mask,' which might significantly impact the upcoming Condensed Face process, even directly governing it.
Buzz! Flashback.
