From my research and imo-only, many psychopathic sexual predators begin their deviant behavior during adolescence(aprox age 14). This is the age that many, if not most cross the threshold from fantasy(many times *advertiser censored* induced)to dark reality. Many, if not most sexual predators/serial killers have two selves; good Jesse is empathetic, selfless, polite, courteous and shows remorse(teddy bear) and evil Jesse(polar opposites). Evil Jesse does not have empathy for others, is filled with unbridled violent rage, and has no human emotions; analogous to a mountain lion. Evil Jesse would be extremely quick & deep thinking/instinctive, creative, calculating, manipulating, and deflective, imo.
Imo, this may explain the various descriptions of JM by family, friends, and coworkers, etc. They would not have ever been allowed to witness evil Jesse..
Another common denominator that keeps cropping up time and time again since the CA speed freak killers of the 1980s is meth/molly. Although there has been no mention of JM's drug involvement. I wouldn't be surprised if this info emerges eventually..
I had mentioned the cedar tree in the background where MH's remains were located in a previous post. Most folks prolly rolled their eyes and disregarded this observation. Good religious Jesse would have likely shown remorse after evil Jesse's violent murders of his innocent victims.. Burial rituals may be indicated, imo..
