Would it be ethically wrong to purposely scare a cat from sneaking into the clothes dryer by turning the dryer on for a half spin when it decides to jump in?

It doesnt seem like it could hurt the cat if I only let it make a half spin or so. Also as long as I allow it to jump in of its own curiosity, the cat's fear wouldn't be pointed at me, but just the idea that jumping in the dryer can lead to a very scary result.

I'm just wondering if animal lovers world wide would curse me if I did this. Would it be considered a good or bad way to teach the cat not to get in the dryer?

I could be careful and check the dryer, keep the door closed, etc, but it seems over the years there's a possibility that the cat could sneak in and it be turned on without anyone knowing the cat is inside. I always worry about this when turning on my dryer.
