Ancient custom of Mourning the Dead

It has been established that rounding your head in  the fashion of a bowl is wrong, due to the fact that it was practiced by the Egyptians. Another strange customs of these people was that during a mourning process it was the custom to cut the head, beard, and cut the skin.  So my guess to this reason is that the protagonist looked at this act as erratic and his people should not be practiced, and when I think about it that does make sense to help deter random acts like this:


To help me get to this particular point I found another website that helped the reasoning behind the commandment: Firstly, we learn that the prohibition is not necessarily a bowl-cut, but making any baldness around the edges of the head. Secondly, we see that the prohibition is specifically in the context of mourning. That is, one is prohibited to make baldness in the head as an act of mourning "for the dead". In ancient times when someone died the surviving relatives were so distraught that they cut their skin until they bled and shaved bald spots on their head.
