He's an exterminator so I'm sure is used to killing many animals.

However, I feel this could have been dealt with in a more professional manor.

Maybe relocated the nest... however I hear once a human as touched a baby bird, or nest, the mother will have nothing to do with them.

Idk, either way I'm sure there was a better way to "deal" with the problem than just a staple gun.

3 years ago my old dog was having trouble getting up and walking. I knew she had hip trouble but then she also had this huge tumor that came up within a week. It covered her whole stomach. It was seeping out fluids. I was out of work and down. She was suffering. I had her over 10 years a rescue situation. I had to put a bullet in her. So sad. Hardest thing Ive ever done and its still haunts me

Yeah...that's not normal. This dude has issues. Years ago I worked part time in pest control and dealt with birds many times. Most people put the babies either outside or throw the whole nest in a trash bag. Only a psycho would do what he did. The worst thing is possums. They carry disease so you trap and shoot them, or throw the trap with a rope into water and drown them.
