My wife is a phsychologist and tells me that only those whom are mistreated or otherwise traumatized in childhood will become the killing type, although they ALL have the disposition for cereal murder, most will not travel down this path but instead... If by "the big house" you mean where the rock-stars of business and political success reside... They are more likely to be the CEO next door than the gang member next door. Or a president, or the trader next to you (if you are sitting next to one of the true, rare, profitable traders)
