There should be nothing wrong with thinking about crime. Openly discussing and planning a crime...well, that depends on a lot of factors, but there's certainly situations where it should be fine, e.g. kids idly fantasizing about blowing away a school bully without any real means or intention to do so.
But when someone honestly and to the best of their ability attempts to commit a serious crime like murder or child abuse, then yes, absolutely they should be prosecuted. If someone attempts to kill me but screws it up, I don't want them walking free to try again and again until they get it right.
Also bear in mind that, at least in the US, "murder" and "attempted murder" are different crimes, and I'm okay with that.
