Sexual Frustration + Bullying = High School Massacre?

One thing I've realized recently is that most perpetrators of high school massacres don't have girlfriends/never had girlfriends. In contrast to the amount of "bullies" and "gangstas" and other self professed tough guys alot of them seem to have partners or at least get sexual favours yet it is the nerdy/loner types who commit these atrocities.

Anyway, the question I'm trying to answer is that if for example the Columbine High School duo got a good screw or 2 off some of the hot chicks, would they have been so angry and would they have done what they did?
