I've long wondered why it is that, every now and again, some lonely, unbalanced man who finds life too cruel to bear feels compelled to flamboyantly lash out and take a handful of hapless bystanders down with him. Women don't do this, generally opting for pure self destruction--developing eating disorders, self mutilating, dating abusive jerks, downing sleeping pills, etc. (Despondent members of both genders have a ghastly tendency to kill family members, but that's an issue for another day.)  

Any sociobiologists or behavioral psychologists out there have an answer?
