Leonardo da Vinci kocht gekooide vogels op de markt en liet ze vrij.
One of my dads friends tried to do this. She was in some Asian country and saw a stall where they were selling kittens, alive and dead. They were for eating, but being from a western country she didn’t like the idea of kittens being killed and eaten. So she went up to the stall and asked to buy one of the live kittens, thinking she could set it free. And WHOMP! the guy at the stall clubs the kitten and hands her a freshly deceased cat. – BigFatCatInTheSky
