So a thing about 106.
A. That is not canon, there is no such thing as canon when it comes to the SCP Foundation. Yes, that backstory is the most famous and commonly accepted "lore", but there's even a backstory to 106 that says he came from an ancient tribe full of people like him who act like him.
B. If you want to get mad at 106's most famous backstory, get mad at the hundreds of WW1 movies.
