You my dear sir, need to know something about the topic before you speak. If we start with the most obvious, why would a three year old reach for a wii control? Well, because every three year old is a curious little bugger that wants to touch, feel and potentially taste everything they get their hands on. A gun shaped wii-controller is an awesome toy for a three year old (especially a three year old who has seen its parents play with it, pointing it and pulling the trigger at stuff).
As for the whole "firing a gun by accident", it isn't all that hard to see the girl in question sitting down with the gun in her lap and pulling the trigger with the barrel aimed at her. Kids don't always follow the ergonomics created by adults and it isn't improbable that the three year old also managed to turn off the safety by sheer experimentation. That is, if the safety was even on to begin with. Someone who leaves a handgun loaded in the open on a table obviously doesn't have a big regard for firearm safety, even if the actual leaving of the gun on the table might just be a case of absent mindedness.
Anyway, now we get to the real running point. What really bugs me about your post. The implication that parents would be ready to blow their children to kingdom come once the realize the "chores" of being a parent. You see, as anyone who has ever had children can tell you, it is the best thing in their life. No matter how annoying, snotty and bratty their kids are, the parents will love them. It is as hard-coded into the human being as things get. Parents might get frustrated at their children, but only mentally ill parents actually ever consider hurting their children or killing them.
That you and I might sometimes get the feeling of "Can't someone shut that bloody kid up?" when out on town and being close to a particularly annoying kid is in no way transferable to that kids parents. They might be frustrated and emberassed. But there will be absolutely no thought in their about "getting rid of the burden" or "going back to the easy life".
Your thougts are indeed disturbing, luckily however, they are merely the thoughts of someone who doesn't know enough on the subject of parent psychology.
