Indeed. Ted Bundy grew up thinking his mother was his sister. Jeff Dahmer had a pretty average family but was traumatised by his parent's divorce. Everybody's got a history that helps to shape who they become. Many of us here though had dysfunctional and even sometimes abusive childhoods. As such, I don't think this testimony is going to go far to sway the hearts and minds of the WS community.
Just a hunch, from past cases.

Yep, quite honestly I don't think there is a single person on the planet who hasn't had to go through something or another in their lives and yet the vast majority of people do not go on to kill. There is something else in the make up of a killer, i.e. that they are not wired up in the same way as other people, and which has nothing to do with any life experience they may have had (imo, of course!)
