How?

A few years ago, Chris Rock did an HBO special and opened w/ saying that he was a new father to a baby girl. He said that the most important thing he could do in his life was to keep his daughter off the pole. That means to keep her from being a stripper. I am currently pregnant for the 2nd time w/ my third child and the sonogram says its a boy. I'm not worried about Abbey, she's not just a sensible child but also a sensible person. The thing about girls is, they hurt themselves when they're hurting. Boys on the other hand, hurt other people. The question I pose to myself is: as the mother of sons, how do I keep them from hurting others? How many female serial killers have there been? I only know of one. How many female rapists have you heard of? I haven't heard of any. My husband & I don't believe a man can be raped anyway (not a man child but a man) but that's another topic all together. I think, much like Chris Rock, that the most important thing that I can do as a mother to boys is to keep them from being serial killers/rapists. You can't tell me that the parents of some of our most famous serial killers didn't have an inkling as to their kid not being "right". Those parents wouldn't be able to convince me that they didn't suspect somthin' may have been wrong w/ little Billy when they had to start buying him adult dogs instead of puppies because puppy after puppy just kept going "missin'". Or later in life when the other families w/ cats started bringing them in for fear of the neighbor boy lightin' a fire cracker & sticking it in the cats "poop shoot". And finally, when the parent actually investigated the stench coming from the old steamer trunk in the garage and found out it was the remains of every animal in the neighborhood that had ever gone missin', along w/ the signs from the animals saying they had gone missin' in a neat little pile arranged by date. Now I suppose some stuff is normal like burning ants w/ a magnifying glass or my husband said they used to put tad poles on the grill. I'm sure everyone reading this knows or knew at one time, some kid or adult male that you have to hide all flammable liquids, matches & lighters from "cause they just can't help themselves". I won't leave one of my nephews alone w/ my dogs right now & I certainly won't leave him alone w/ my knew baby when he comes. For that matter, I don't think I would even leave him alone w/ my 2 year old. Is it a demon that causes serial killers & serial rapists to become what they are or is it environment & genetics? Maybe its a little from column A & a little from column B.
