My LE hubby and I were just saying, "If this INDEED BSLs real dad, then BSL would be the example of the so called "gene" or "programmed" to kill...or as hubby said, "His medulla oblungatta was not programmed for rays of sunshine!" I know people don't have a per say that part, but I've seen scans of brains from criminals that particular areas DO light up when anger, aggression or the likes is introduced to them. If birth momma was also a rape Vic of KM, then that "unwanted, rejected, useless" feeling consumed this dude too. So, for the sake of an example and JMOO, he had the strikes against him. Born of rage, rape and rejection. He then turns those things into a real "thing" in his life. It's like Bundy, he was (so said) born of incest; then after he was born, his mother passed him off as her brother (which if it was incest, he was but also her son). I was also told that BSLs dad (the one alive) and the step-dad ARE related...again, confusion. Family dynamics are not "normal".
My cousin and her brothers and sister were victims of incest. She and her sister are now serving time (one in Tx, the other in La) for murdering their momma. I was told by family that she had pinned up rage from as a kid that it finally caused her to snap. She, even passed that "way of life" down to her kids (oldest daughter got preggo for step-dad)...it's a cycle that if not broken will continue. Again, JMOO from my studies.
