Killing of tigresses in Maharashtra and Lucknow was sad. It's sad because tigers are endangered species of animals. We are trying hard to conserve them. In my opinion if Avni had become man eater then she could have been captured and sent to the Zoo or any other places like this.
Also as animals don't have the brain like us so we sympathise more with them as we expect such things from them but not from the human beings.

I agree tigers are endangered species of animals. One should protect them. But when Tiger is going on a killing spree and the specialists are not able to control there is no other option than killing it. As mentioned by the author the animals are becoming more important than human beings as human beings are plenty. It may not matter even we lose a few persons.
Anyhow it is sad that the Tiger killed many individuals after turning to be a man-eater. The forest law enforcement officials might have reacted well in advance and might have taken Tiger into their fold so that no damage to human beings. Now we lost many people and a tiger also.
