The most recent one for me is the father in Colorado who killed his wife and kids. I can not understand why people kill their children.
"- The man perceives the woman to be his whole world so that he feels that any separation from her entails a loss of his own identity ;
- The man's life lacks other sources of meaning and reasons for living;
- The man's traditional perception of masculinity, which dictates that the male has full power, honor, and control, runs counter to his dependency upon his wife, making that reliance appear evidence of his weakness and humiliation, and an affront to masculine honor.
- The man's personal behavior is rigid and uncompromising
- The man's prevailing beliefs about love appear to justify the sacrifice of his wife on the one hand and of persistence on the other. In this case, the ideology behind love provides the "legitimacy" for terrible crimes [in his mind].
When all the above conditions pertain, the risk of wife murder significantly increases. The specific event that ignites the explosive barrel often revolves around the woman threatening to or actually separating from her partner."
