The result does not justify the action

Couple nights ago, I had to discipline my 5 years old daughter.

She loves our Alexa and Google at home to read stories to her. This behavior discourages her reading habit, so I decided to unplug Google.

I have always been emphasizing on safety around the house (i.e stay away from wall plug)
That night, Tiara ran to me and said "Mommy, I plug in Google and I did not get zapped"

While I am glad that she is safe, I told her, the result that she is not getting zapped does not justify her disobedience of first- leaving Google alone and 2nd being not safe.

I had to discipline her so that she remember to be safe.
These boundaries are created for her safety.
