Sexual desires and illegal affairs as agents for murders.. 

If we take sexual desires and illegal affairs as catalyst to murder cases they have the greatest share rather than any other,even they serve to the prior mentioned issues as well. If we take the illegal affairs they do obviously  has the greatest proportion than any other. In the very basic form of understanding"Illegal" suggest it is not to be done, but it is the untamed instinct of human kind to Do what should be not done, thus they cross the boundaries regardless of another aspects. If its illegal they suppose to remove the person who has the legal claim. Because its their only barrier. When they involve in this brutal process if its a spouse first they will try to end up with him/her with the help of the other , but most of the time it ironically happens the other way round making it the last for many lives including children and many others. 

At times these illegal affairs might come to a place where one get backs the proper consciousness and undo with what has been done,moving into the interest of others, but its too late when they realize what is done can not be undone, as its not the decision of the both. Thus,sooner the other feel the sex jealousy  which make them drive crazy for not wanting to loose and share what is once yours. They quickly grows irrational ,if they can not win with the consent,they move on to win it the other way by forcibly, where in most cases they end up being murderers and even commit suicide. so this is all a chain that is integrated together one consequently leading to the other.

Actually the unfulfilled desires and wishes have a direct connection to the sexual desires. Sexual desires are a very dangerous aspect which mostly affect the women. The huge murder trend that occurred  in Kahawatta area was due to the sexual trauma,where a certain group of men killed women to fulfill their desires. When the sociologist moved on to the background of this they found that most of the people in that village were married at the very young age of sixteens and seventeens and they were quite lack of education, while the temple of the village and police had no proper sounding interconnection with each other. In the society if a woman is alone most men think that they have a right to claim over her body thinking that its a public property now,if she is unwilling they would mostly rape her  fulfill both their desires and avenge on her turning back to them.

I think we can reduce these things to a certain extent if we are more careful and be alert to what is happening in the society and be wise in our sudden decisions to have all the comforts in the world.
